ModuleNotFoundError

Python raises a module not found error when it cannot find the library (i.e., the module) mentioned in an import statement.

A module not found error is a special kind of import error.

Note that the text of the error message depends on the implementation. Different versions of Python and different checking tools will give slightly different messages.

Examples

Code

from pitamaro import rectangle

error

ModuleNotFoundError: No module named 'pitamaro'

Code

import maths

ModuleNotFoundError: No module named 'maths'
