Importing Bash Variables

To import a Bash variables to a python script, you can make use of environment variables by following the steps below:

  1. In your Bash script, export the variable as an environment variable using the export command. For example, let's say you want to export a variable called MY_VARIABLE:

    export MY_VARIABLE="Hello, World!"
  2. In your Python script, you can access the environment variable using the os module. Import the os module at the beginning of your Python script:

    import os
  3. Access the environment variable using the os.environ dictionary, which provides access to all the environment variables. Retrieve the value of the variable using its name:

    my_variable = os.environ.get('MY_VARIABLE')

    The os.environ.get() function retrieves the value of the environment variable specified by the argument (MY_VARIABLE in this case). It returns None if the variable is not found.

  4. Now, you can use the my_variable variable in your Python script:

    print(my_variable)  # Output: Hello, World!
  5. To run the scripts, you can also execute the following commands in the terminal:

    $ source script.sh   # Set the Bash variable
    $ python script.py # Run the Python script

    The output will be:

    Hello, World!

    By sourcing the Bash script, the environment variable is made available to the Python script. The Python script then accesses the value of the environment variable using os.environ.get().
