What happens when a function tries to assign or change a value of a variable that has been defined at the module level?

Question

Answer

Python creates a temporary variable with the same name, and the value of that variable exists only within the scope of the function.

Answer

The function succeeds, because the module variable is considered global in scope.

Answer

The function fails, and an out of scope error message is raised.

Answer

The function succeeds, but the value is appended to the variable.
