TypeError in Python — What It Means and How to Fix It

What Python's TypeError exception means and how to resolve it.

Published October 27, 2026

TypeError is raised when an operation or function is applied to a value of an inappropriate type.

Key points

  • Catch it specifically with "except TypeError:" when you want to handle this exact case rather than a bare except

Example

'2' + 2  # TypeError: can only concatenate str (not "int") to str
