我想防止两次打印 [英] I want to prevent printing twice

问题描述

昨天，一个感激的人帮助我解决了这个问题，但是又被封锁了.如果像下面的图片一样打印出来，部分error! ~将被输出两次.如果更改if之后写入的内容和else写入的内容的顺序，则会打印两次.我该如何解决?

Yesterday, I was helped by a grateful person to solve the problem, but it was blocked again. If I print it out like the picture below, the part error! ~ is output twice. If I change the order of what is written after if and what else is written, it is printed twice. How can I solve this?

推荐答案

这是因为您两次运行该函数，一次在if语句中，一次在打印中.将其存储在这样的变量中:

This is because you are running the function twice, once in the if statement, and once in the print. Store it in a variable like so:

# ...

for i in range(0, 5):

    # ...
    # ...

    bibeon = input("Enter password: ")
    chkResult = passwordChk(bibeon)
    if chkResult == 'Valid Password':
        print(chkResult)
        break
    else:
        print(chkResult)
