SimFin is a database with financial data such as Income Statements, Balance Sheets and Cash Flow Statements, along with a simple Python API for downloading and using the data. These tutorials show how to use the SimFin API and data.

If you want to run these tutorials on your own computer, then it is recommended that you download the whole repository from GitHub, instead of just downloading the individual Python Notebooks.
The easiest way to download and install this is by using git from the command-line:
git clone https://github.com/simfin/simfin-tutorials.git
This creates the directory
simfin-tutorials and downloads all the files to it.
This also makes it easy to update the files, simply by executing this command inside that directory:
You can also download the contents of the GitHub repository as a Zip-file and extract it manually.
If you want to run these tutorials on your own computer, then it is best to use a virtual environment when installing the required packages, so you can easily delete the environment again. You write the following in a Linux terminal:
Or you can use Anaconda instead of a virtualenv:
conda create --name simfin-env python=3
Then you switch to the virtual environment and install the required packages.
source activate simfin-env pip install -r requirements.txt
When you are done working on the project you can deactivate the virtualenv:
How To Run
Once you have installed the required Python packages in a virtual environment,
you run the following command from the
simfin-tutorials directory to view
and edit the Notebooks:
source activate simfin-env jupyter notebook
Run in Google Colab
If you do not want to install anything on your own computer, then the Notebooks can be viewed, edited and run entirely on the internet by using Google Colab.
You can click the "Google Colab"-link next to the tutorials listed above. You can view the Notebook on Colab but in order to run it you need to login using your Google account.
All the required Python packages should already be installed on Google Colab, except for simfin which you can install by executing the following command at the top of the Notebook:
!pip install simfin
If that is insufficient, then you can clone this entire GitHub repository to your Google Colab account, and execute the following commands at the top of the Notebook, to install all requirements:
# Clone the repository from GitHub to Google Colab's temporary drive. import os work_dir = "/content/simfin-tutorials/" if not os.path.exists(work_dir): !git clone https://github.com/simfin/simfin-tutorials.git os.chdir(work_dir) # Install the required Python packages. !pip install -r requirements.txt
Note that you will need to run this every time you login to Google Colab.
All the Notebooks can be run automatically and tested for errors. This is particularly useful for developers who are making changes to the simfin package, because it complements the unit-tests and data-tests with more realistic use-cases.
First you need to install nbval:
pip install nbval
Then you can execute all the Notebooks and test them for errors by running the following command from the directory where the Notebooks are located:
pytest --nbval-lax -v
Note that this will only test for errors and exceptions. It will not test whether the new output matches the old output found in the Notebooks, because the datasets are continually updated.
