Introduction to Python Programming Live Training

This is the code for the Safari Live Training - Introduction to Python Programming presented by Arianne Dee

Before the class, please follow these instructions:

  1. Install Python
  2. Install PyCharm
  3. Download the code
  4. Check that Python was installed properly

Set up instructions

1. Install Python 3.6 or higher

Go to https://www.python.org/downloads/

Click the yellow button at the top to download the latest version of Python.

On Mac or Linux

Follow the prompts and install using the default settings.

On Windows

The default settings don't add Python to your PATH so your computer doesn't know where to look for it when Python runs (for some inexplicable reason).

If you're just installing Python now

Follow the instructions here: Windows Python installer instructions

If you've already installed Python with the default settings

Follow the instructions here: Add Python to PATH variable in Windows

2. Download PyCharm (Community Edition)

Download here: https://www.jetbrains.com/pycharm/download/

Install, open, and use the default settings.

3. Download the course files

If you're viewing this on GitHub already, stay on this page. Otherwise, go to the GitHub repository: https://github.com/ariannedee/intro-to-python

If you know git:

Clone the repository.

If you don't know git:

  1. Click the "Clone or download" (green) button at the top-right of the page
  2. Click "Download ZIP"
  3. Unzip it and move the intro-to-python-master folder to a convenient location

4. Make sure that Python is properly installed

  1. Open the Command Prompt application in Windows or Terminal on Mac or Linux

  2. Type python --version and press enter

  3. Type python3 --version and press enter

  4. One or both of those commands should print a Python version of 3.7.1 or higher (whichever version you just downloaded)

Note: You can now type just the python or python3 command in Command Prompt or Terminal to run the Python interpreter. You can also run a .py file by running python filename.py

FAQs

Can I use Python 2?

Yes, but I highly recommend using Python 3. If you are using Python 2, a few commands will be different. I will mention them throughout the class.

Can I use a different code editor besides PyCharm?

Yes, but it is only recommended if you are already know it and are comfortable navigating to different files and running commands in the command line. If it has syntax highlighting for Python, that is ideal.

PyCharm can't find Python 3

On a Mac:

  • Go to PyCharm > Preferences

On a PC:

  • Go to File > Settings

Once in Settings:

  • Go to Project: intro-to-python > Project Interpreter
  • Look for your Python version in the Project Interpreter dropdown
  • If it's not there, click gear icon > Add...
  • In the new window, select System Interpreter on the left, and then look for the Python version in the dropdown
  • If it's not there, click the ... button and navigate to your Python location
  • You may have to search the internet for where Python gets installed by default on your operating system
You can’t perform that action at this time.
