Eu tenho uma pergunta simples em Python na qual estou congelando o cérebro. Este trecho de código funciona. Mas quando substituo "258 494-3929" por phoneNumber, recebo o seguinte erro abaixo:

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

A propósito, eu fizimport re e tentei usarrstrip no caso de\n
O que mais eu poderia estar perdendo?

 # 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
