REST APIs with Flask and Python - Imports in Python

This video tutorial covers the basics of importing in Python, including how to import functions from other files, the role of the __name__ variable, and how Python determines import paths. It also explains the use of __init__.py for importing from folders and how to check imported modules using sys.modules. The tutorial provides practical examples and clarifies common import-related concepts.

What is the purpose of the __name__ variable in Python?

• To differentiate between the file being run and the file being imported

• To store the name of the module

• To define the main function of a module

• To keep track of the number of imports

How can you import a specific function from a module in Python?

• import mymodule

• from mymodule import *

• from mymodule import function_name

• import function_name from mymodule

What happens to the __name__ variable when a module is imported?

• It is deleted

• It changes to the module's name

• It remains unchanged

• It becomes '__main__'

Where does Python first look for modules to import?

• In the user's home directory

• In the system's root directory

• In the Python installation directory

• In the current working directory

How can you modify the search path for Python modules?

• By editing the Python source code

• By using the sys.path.append() method

• By renaming the module

• By changing the file extension

What is the role of an __init__.py file in a Python package?

• To initialize the package

• To store package metadata

• To make the directory a package

• To define the package's main function

Why does Python keep track of imported modules?

• To manage memory usage

• To ensure module security

• To speed up the import process

• To prevent duplicate imports
