Some online services offer the opportunity to run Python code without having to install anything on your machine.
If you wish to run OpenFisca directly on your browser for a simulation or to evaluate the impact of a reform, you might find one of the following services useful: Gitpod, repl.it, python anywhere and Jupyterlab.
Please be aware that you might need to install the OpenFisca package you need on your online service before using it. You will find a quick generic usage example to test your setup below.
Start by installing the package you need on your online service e.g. OpenFisca-Country-Template.
Write the code you wish to run. Example of a code snippet to run:
from openfisca_country_template import CountryTaxBenefitSystem
tax_benefit_system = CountryTaxBenefitSystem()
parameters = tax_benefit_system.parameters
print(parameters)
Run your code and check the results.
