仅输入字符串 [英] input string only

问题描述

我如何要求用户只输入字符串.如果没有这样的东西，我如何设置它，以便如果他们输入任何其他内容，它会要求用户重新输入.

How do I ask the user to input the string only. If there isn't such a thing how do I set it so that if they enter anything else it would ask the user to re-enter.

这是我尝试过的(不起作用):

This is what I have tried (it doesn't work):

name = raw_input("Enter name: ")
 if name != str(name):
     name = raw_input("Error, please re-enter : ")

推荐答案

while True:
    userInput = raw_input("Enter a string only")
    if type(userInput) not str:
        continue
    else:
        print "You entered a STR data type. Congratulations"
        break
