How can I use environment variables in my scripts?

You can access environment variables in your scripts using the syntax specific to your programming language. For example, in Python, you can use the os module.

Can you show me a Python example?

Sure! Here's a simple example:

import os

# Get the value of the environment variable
my_var = os.getenv('MY_VARIABLE')
print(f'The value of MY_VARIABLE is: {my_var}')

What if the variable is not set?

If the variable is not set, os.getenv() will return None by default. You can also provide a second argument to return a default value.

Thanks! How do I set environment variables?

You can set environment variables in your terminal using the export command in Unix/Linux or set in Windows. For example, export MY_VARIABLE=value.
