How do I set environment variables in Python?
You can set environment variables in Python using the os
module. For example, you can use os.environ['VAR_NAME'] = 'value'
.
Can you show me an example of how to read an environment variable?
Sure! You can read an environment variable using os.getenv('VAR_NAME')
. It will return the value of the variable.
What if the environment variable doesn't exist?
If the environment variable doesn't exist, os.getenv('VAR_NAME')
will return None
by default, or you can provide a second argument to return a default value.
