Title: Python: Calling Functions from Another File Without Importing
Introduction:
In Python, it's a common practice to organize code into separate files for better maintainability and readability. Normally, functions defined in one file can be accessed in another file by importing the module. However, there might be scenarios where you want to call a function from another file without importing the entire module. This tutorial will guide you through a technique to achieve this using the exec() function.
Step 1: Create the source file
Let's start by creating two Python files: caller.py and callee.py.
callee.py:
caller.py:
Step 2: Call the function without importing
Now, let's write the code in caller.py to call the functions defined in callee.py without importing the module.
Explanation:
Conclusion:
While calling functions from another file without importing is possible using the exec() function, it's essential to use this technique cautiously, as it can make the code less readable and harder to maintain. Importing modules remains the standard and recommended practice for organizing and accessing code in Python.
