调用函数时的语法错误

Question

quiz_again = str(input("Enter yes or no")
if quiz_again == "yes":
                 quiz()

I am tying to run this on python (idle version 3.4.2) but I am greeted with syntax error: invalid syntax and the cursor highlights the ":" If anyone could explain I would be very appreciative

Answer 1

You have an indentation issue. If a function quiz is defined, try it:

quiz_again = str(input("Enter yes or no"))
if quiz_again == "yes":
    quiz()

or it's possible to run:

quiz_again = str(input("Enter yes or no"))
if quiz_again == "yes": quiz()

Answer 2

正如Jim所指出的，您需要编写为：

quiz_again = str(input("Enter yes or no"))
