The Switch-case statement is a powerful and rapid programming feature that allows users to change the flow of their program based on the value of a variable or expression. In Case 1, Python evaluated true_func(). Since it returns True, the next operand (false_func()) is not evaluated. Notice that the phrase Running false_func() is never printed. Finally, the whole expression is considered True. Case 2 evaluates both functions, because the first operand (false_func()) is False.
