我有一个简单的Python问题，我的大脑停滞不前。此代码段有效。但是，当我用phoneNumber替换“ 258 494-3929”时，出现以下错误：

# 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: "))  
    File "<string>", line 1  
      258 494-3929  
          ^
  SyntaxError: invalid syntax

顺便说一句，我没有import re和尝试使用rstrip的情况下\n

我还能缺少什么？
