Fixing the ImportError: No module named ***** in Python

One of the errors you may encounter while working with Python is ImportError: No module named *****. This common issue often arises when the Python interpreter cannot locate the specified module. In the context of running a script like addition.py, understanding why this error occurs and how to rectify it can save you a lot of debugging time. Here are some steps to help you resolve this error.

Understanding the ImportError

Python uses the import statement to bring in modules and packages. When the interpreter tries to execute an import statement and the module isn't found, it raises an ImportError. The error message specifically mentions the name of the module that couldn’t be found, making it easier to identify which import is causing the issue.

Common Causes

Several factors can lead to an ImportError. Here are some of the most typical reasons:

Misspelled Module Name: If the module name specified in the import statement is incorrect, Python will not be able to find it.

Module Not Installed: The module you're attempting to import may not be installed in your Python environment.

Incorrect Environment: You might be running the script in an environment where the required module is not installed.

Relative Imports: When working in packages, using relative imports incorrectly can lead to import errors.

Steps to Fix the ImportError

Check for Typographical Errors:
Ensure that the module name in the import statement is spelled correctly:
