This will be an intensive seven weeks. We expect that your attendance of lectures plus homework time might average 50-60 hours per week of work.

We have provided 6 areas of tutorials that you will benefit from reading and working through before the training. We will, of course, teach these things as we go through the material. But we will be able to proceed at a faster pace if the attendees are already familiar with most of the concepts below.

Pre-course Tutorial Areas

  1. Instructions for installing the Anaconda distribution of Python
  2. Text editor suggestions (Atom, Sublime Text 3, Vim)
  3. PEP8, docstring commenting, and module structure
  4. Git and GitHub tutorial
  5. Jupyter Notebooks
  6. Basic Python tutorials (data structures, logic, functions and modules, pandas, root finders and minimizers)

3. Instructions for installing the Anaconda distribution of Python

We will be using the Python programming language and many of its powerful libraries for writing the code that will run most of the computational methods we will use during the Boot Camp. Using an open source language, such as Python, has the advantage of being free and accessible for anyone who wishes to learn these materials or contribute to these projects. Being open source also allows Python users to go into the source code of any function to modify it to suit one's needs.

We recommend that each participant download the Anaconda distribution of Python provided by Anaconda, Inc.. We recommend the most recent stable version of Python, which is currently Python 3.6. This can be done from the Anaconda download page for Windows, Mac OSX, and Linux machines.

4. Text editor suggestions

In our recommended Python development workflow, you will write Python scripts and modules (*.py files) in a text editor. Then you will run those scripts from your terminal. You will want a capable text editor for developing your code. Many capable text editors exist, but we recommend three.

  1. Atom
  2. Sublime Text 3
  3. Vim

Atom and Vim are completely free. A trial version of Sublime Text 3 is available for free, but a licensed version is $80 (US dollars). In the following subsections, we give some of the details of each of the above three text editors.

4.1. Atom

Atom is an open source text editor developed by people at This editor has all the features of Sublime Text 3, but it also allows users full customizability. Further, it has been a while now that the users of Atom have surpassed the critical mass necessary to keep the editor progressing with the most cutting edge additions.

There are several packages you'll want to install with Atom. Once Atom is installed, you can add packages by navigating Atom->Preferences->Install and then typing in the name of the package you would like to install.

For work with Python, we recommend the following packages be installed:

  • MagicPython
  • python-indent
  • tabs-to-spaces
  • minimap
  • open-recent
  • linter-python-pep8

For development with GitHub we recommend:

  • merge-conflict

If using LaTex in this editor, the following packages are helpful:

  • atom-latex
  • latextools
  • autocomplete-bibtex
  • dictionary
  • latexer
  • pdf-view

In addition, you will also want to download the Skim PDF viewer to aid in displaying PDF files compiled from TeX with Atom.

4.2. Sublime Text 3

Sublime Text 3 is the most widely used and versatile private software text editor. It has tremendous flexibility, as well as the polish of a piece of professional software. Sublime Text 3 will cost $80 for a license, although you can use a trial version indefinitely without charge while only having to suffer through frequent reminders to buy the full version.

4.3. Vim

Vim is free and very powerful. Vim is the hard-core developer's text editor of choice. The learning curve for using vim is a little steeper than that of Atom and Sublime Text 3, but it also has some advantages for efficient programming. Vim has navigation that does not use a mouse or trackpad. Eventually, your fingers never leave your keyboard. Further, most terminals have Vim built in so you can more easily use Vim to edit scripts and modules on the fly with your terminal session.

5. PEP 8, docstring commenting, and module structure

Computer code executes some set of commands in an organized way. In every case, there are often many ways to execute a set of instructions--some ways more efficient than others. However, code has at least three functions.

  1. Efficiently execute the task at hand.
  2. Be accessible and usable to other programmers.
  3. Be scalable and integrable with other projects and procedures.

Bill Gates is credited with the following plea for efficiency and parsimony in code writing.

"Measuring programming progress by lines of code is like measuring aircraft building progress by weight."

Strong support for points (2) and (3) is Eagleson's Law.

"Any code of your own that you haven't looked at for six or more months might as well have been written by someone else."

Because of the latter two characteristics, Python code has developed some conventions and best practices, some of which have been institutionalized in the PEP 8--Style Guide for Python Code ("PEP" stands for Python Enhancement Proposals). Key examples PEP 8 Python coding conventions are the following.

  • Indents should be 4 spaces (not tab)
  • Limit all lines to a maximum of 79 characters long blocks of text being limited to 72 characters (Evans limits all his lines to 72 characters)
  • Use a space after a comma
  • Use a space before and after arithmetic operators

In the text editors Atom, Sublime Text 3, and Vim, you can install Linter packages that highlight areas of your code that break PEP 8 rules and tell you what the violation is.

There are fewer conventions in docstring structure, but we have developed some of our own that are outlined in the PythonFuncs.ipynb Jupyter notebook. See especially Sections 3 and 4 of the Jupyter notebook.

6. Using LaTeX

You will turn in all of your assignments by using the LaTeX document preparation platform. LaTeX produces documents with a sophisticated mathematical equation engine. Because LaTeX is standard in mathematical and theoretical document exposition, we will be using it in this class. The LaTeX tutorial PDF chapter in the /Tutorials/LaTeX/ directory is a great reference for installing and running LaTeX. We have also included in that directory a template LaTeX_probset_template.tex as well as the PDf file (LaTeX_probset_template.pdf) generated by compiling that .tex file.

7. Git and GitHub tutorial

We have included a tutorial on using Git and in the Tutorials directory of this repository. Git is a powerful version control software that comes natively installed on many machines and is widely used. is the most widely used online platform for hosting open source projects and integrating with Git software. Git has a significant learning curve, but it is essential for large collaborations that involve software development.

A more comprehensive Git resource is Pro Git, by Chacon and Straub (2014). This book is open access, and is available online at But Evans likes having it in his library in hard copy. This book is the difinitive guide with everything Git, and it has as its primary application the interaction between Git and GitHub. However, the workflow described in the tutorial above was hard to find in this Git book.

8. Jupyter Notebooks

Jupyter notebooks are files that end with the *.ipynb suffix. These notebooks are opened in a browser environment and are an open source web application that combines instructional text with live executable and modifyable code for many different programming platforms (e.g., Python, R, Julia). Jupyter notebooks are an ideal tool for teaching programming as they provide the code for a user to execute and they also provide the context and explanation for the code. We have provided a number of Jupyter notebooks in the Tutorials folder of this repository.

These notebooks used to be Python-specific, and were therefore called iPython notebooks (hence the *.ipynb suffix). But Jupyter notebooks now support many programming languages, although the name still pays homage to Python with the vestigal "py" in "Jupyter". The notebooks execute code from the kernel of the specific programming language on your local machine.

Jupyter notebooks capability will be automatically installed with your download of the Anaconda distribution of Python. If you did not download the Anaconda distribution of Python, you can download Jupyter notebooks separately by following the instructions on the Jupyter install page.

8.1. Opening a Jupyter notebook

Once Jupyter is installed--whether through Anaconda or through the Jupyter website--you can open a Jupyter notebook by the following steps.

  1. Navigate in your terminal to the folder in which the Jupyter notebook files reside. In the case of the Jupyter notebook tutorials in this repository, you would navigate to the ~/BootCamp2018/Tutorials/ directory.
  2. Type jupyter notebook at the terminal prompt.
  3. A Jupyter notebook session will open in your browser, showing the available *.ipynb files in that directory.
  • In some cases, you might receive a prompt in the terminal telling you to paste a url into your browser.
  1. Double click on the Jupyter notebook you would like to open.

It is worth noting that you can also simply navigate to the URL of the Jupyter notebook file in the GitHub repository on the web (e.g., You can read the Jupyter notebook on, but you cannot execute any of the cells. You can only execute the cells in the Jupyter notebook when you follow the steps above and open the file from a Jupyter notebook session in your browser.

8.2. Using an open Jupyter notebook

Once you have opened a Jupyter notebook, you will find the notebook has two main types of cells: Markdown cells and Code cells. Markdown cells have formatted Jupyter notebook markdown text, and serve primarily to present context for the coding cells. A reference for the markdown options in Jupyter notebooks is found in the Jupyter markdown documentation page.

You can edit a Markdown cell in a Jupyter notebook by double clicking on the cell and then making your changes. Make sure the cell-type box in the middle of the top menu bar is set to Markdown. To implement your changes in the Markdown cell, type Shift-Enter.

A Code cell will have a In [ ]: immediately to the left of the cell for input. The code in that cell can be executed by typing Shift-Enter. For a Code cell, the cell-type box in the middle of the top menu bar says Code.

8.3. Closing a Jupyter notebook

When you are done with a Jupyter notebook, you first save any changes that you want to remain with the notebook. Then you close the browser windows associated with that Jupyter notebook session. You should then close the local server instance that was opened to run the Jupyter notebook in your terminal window. On a Mac or Windows, this is done by going to your terminal window and typing Cmd-C or Ctrl-C and then selecting y for yes and hitting Enter.

9. Python tutorials

For this training, we have included in this repository six basic Python tutorials in the Tutorials directory.

  1. PythonReadIn.ipynb. This Jupyter notebook provides instruction on basic Python I/O, reading data into Python, and saving data to disk.
  2. PythonNumpyPandas.ipynb. This Jupyter notebook provides instruction on working with data using NumPy as well as Python's powerful data library pandas.
  3. PythonDescribe.ipynb. This Jupyter notebook provides instruction on describing, slicing, and manipulating data in Python.
  4. PythonFuncs.ipynb. This Jupyter notebook provides instruction on working with and writing Python functions.
  5. PythonVisualize.ipynb. This Jupyter notebook provides instruction on creating visualizations in Python.
  6. PythonRootMin.ipynb. This Jupyter notebook provides instruction on implementing univariate and multivariate root finders and unconstrained and constrained minimizers using functions in the scipy.optimize sub-library.

To further one's Python programming skills, a number of other great resources exist.

In addition, a number of excellent textbooks and reference manuals are very helpful and may be available in your local library. Or you may just want to have these in your own library. Lutz (2013) is a giant 1,500-page reference manual that has an expansive collection of materials targeted at beginners. Beazley (2009) is a more concise reference but is targeted at readers with some experience using Python. Despite its focus on a particular set of tools in the Python programming language, McKinney (2018) has a great introductory section that can serve as a good starting tutorial. Further, its focus on Python's data analysis capabilities is truly one of the important features of Python. Rounding out the list is Langtangen (2010). This book's focus on scientists and engineers makes it a unique reference for optimization, wrapping C and Fortran and other scientific computing topics using Python.

10. Other Books

Students participating in the Boot Camp need to obtain their own copy of the math book Humpherys, et al (2017). This book can be purchased through SIAM or Amazon. We will provide printed copies of the second volume of the book, Humpherys, et al (2018).

The following books are recommendation that will not be required, but that are valuable in the library of a dynamic economist. We will also cover real analysis topics in measure theory. We recommend the following two books for their background on measure theory. Ok (2007) is a great real analysis book for economists. Kolmogorov and Fomin (1979) is a great real analysis book, the last four chapters of which are a good foundation for measure theory. Stokey and Lucas (1989, chap. 7) has an exposition of how measure theory gets used in dynamic stochastic macroeconomic theory. Stokey and Lucas (1989) is probably a good book for any macroeconomist to have in their library. On the economics side, some additional books that we like and recommend are Ljungqvist and Sargent (2012) and Adda and Cooper (2003).

11. C++ tutorials

Although we will be using Python for most of the Boot Camp, we will use some C++ for the computational labs taught by Simon Scheidegger on July 10, 12, 17, and 19. These computational labs treat high performance computing, parallel computing, and high dimensional approximation. Using supercomputing resources is much more flexible and accessible with C++.
