🌳 Environment Variable

  • Solo, at your own pace

🎯 Learning Objective​

  • Use environment variables in PowerShell and Python.

📜 Instructions​

Step 1​

Write a Python script that saves environment variables to a JSON file. You can use the os module to access environment variables.

Step 2​

  • Run the Python script you wrote in Step 1 in PowerShell.
  • Make a copy of the generated JSON file.
  • Add an environment variable in PowerShell and rerun the Python script.
  • Verify that the environment variable has been added to the JSON file.

Step 3​

Modify your script to read the environment variable MYAPP_MODE which will be either dev or prod. Depending on the value of this variable, the script should display a different message in the console.

Step 4​

Test your script by setting the environment variable MYAPP_MODE to dev and running it. Then change the variable to prod and run the script again. Ensure that the displayed message corresponds to the variable's value.
