Question 1

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

Accepted Answer

A)  The function succeeds, because the module variable is considered global in scope. 
B)  The function succeeds, but the value is appended to the variable. 
C)  The function fails, and an out of scope error message is raised. 
D)  Python creates a temporary variable with the same name, and the value of that variable exists only within the scope of the function.
