问题描述

我有一个简单的 Python 问题，我脑子都被冻结了.此代码片段有效.但是当我用电话号码替换258 494-3929"时，出现以下错误:

I have a simple Python question that I'm having brain freeze on. This code snippet works. But when I substitue "258 494-3929" with phoneNumber, I get the following error below:

# Compare phone number  
 phone_pattern = '^d{3} ?d{3}-d{4}$'

 # phoneNumber = str(input("Please enter a phone number: "))

 if re.search(phone_pattern, "258 494-3929"):  
        print "Pattern matches"  
  else:  
        print "Pattern doesn't match!"

 Pattern does not match  
 Please enter a phone number: 258 494-3929  
 Traceback (most recent call last):  
    File "pattern_match.py", line 16, in <module>  
      phoneNumber = str(input("Please enter a phone number: "))

顺便说一下，我做了 import re 并尝试使用 rstrip 在

By the way, I did import re and tried using rstrip in case of the

我还能缺少什么?

推荐答案

你应该使用 raw_input 而不是 input，你不必调用 str，因为这个函数本身返回一个字符串:

You should use raw_input instead of input, and you don't have to call str, because this function returns a string itself:

phoneNumber = raw_input("Please enter a phone number: ")
