Evaluate doesn't work for statement that needs user input

[QiangF]

For example:

while True:
    try:
        n = input("Please enter an integer: ")
        n = int(n)
        break
    except ValueError:
        print("No valid integer! Please try again ...")
print("Great, you successfully entered an integer!")

The desired behavior is to switch to the python process buffer and wait for user input
