__import__

Why alx always use add_integer = __import__(‘0-add_integer’).add_integer

When you try this in your Python shell

>>> from 0-add_integer import add_integer
  File "<stdin>", line 1
    from 0-add_integer import add_integer
         ^
SyntaxError: invalid syntax

The error you are encountering is a SyntaxError caused by the use of an invalid syntax in your import statement. Python does not allow module or variable names to start with a numeric digit, hence the error message.

To resolve this issue, you can rename the 0-add_integer module to a valid name without starting with a digit. For example, let’s assume you rename it to add_integer_module. Then, you can modify your import statement accordingly:

from add_integer_module import add_integer

Make sure that the renamed module file (add_integer_module.py) is present in the same directory as your script or accessible in the Python module search path.

>>> add_integer = __import__('0-add_integer').add_integer

This works just perfectly
Now you understand why alx uses it in all test files
