Frequently Asked Questions ( FAQs )
What do you mean by OS environment?
The Operating System (OS) environmental or OS environ means or OS environ define the software and hardware infrastructure that enables computer programs to run. It includes the OS kernel, system libraries, and device drivers, providing an interface for application software to interact with the computer hardware.
How can I access environment variables in Python?
In Python, you can access environment variables using the `os` module. By using os.environ, we can access a dictionary-like object containing environment variables. For example, `value = os.environ.get(‘VARIABLE_NAME’)` retrieves the value of the specified environment variable.
Python | os.environ object
os.environ in Python is a mapping object that represents the user’s OS environmental variables. It returns a dictionary having the user’s environmental variable as key and their values as value.
os.environ behaves like a Python dictionary, so all the common dictionary operations like get and set can be performed. We can also modify os.environ but any changes will be effective only for the current process where it was assigned and it will not change the value permanently.
