TypeError: object is not callable

Qué causa este error

You used parentheses on a non-callable object. This happens when a variable shadows a function name (e.g., str = 'hello'; str(42)), accessing a property instead of a method, or accidentally overwriting a function.

Cómo solucionarlo

Check that the variable has not been reassigned from a function to a value. Rename variables that shadow built-in functions. Use callable(obj) to check before calling. Restart the interpreter if you shadowed a built-in.

x = 5; x()  # TypeError: 'int' object is not callable
