So, let’s learn about local and global variables in Python. 1. Local Variables in Python A variable that is declared inside a Python function or module can only be used in that specific function or Python Module. This kind of variable is known as a local variable. Example: Python 1...

Within a module, the module’s name (as a string) is available as the value of the global variable __name__. The code in the module will be executed, just as if you imported it, but with the __name__ set to "__main__". ...
When a module is imported the interpreter first searches for a built-in module with that name. If not found, it then searches in a list of directories given by the variablesys.path. Thesys.pathis a list of strings that specifies the search path for modules. It consists of the current ...
After starting the interactive Python interpreter, you imported the requests module. By calling requests.__version__, you verified that you were using the same version of requests as you expected. You also investigated requests.__file__ to confirm that you’ve imported the requests module from ...
