命令行输入导致SyntaxError [英] Command-line input causes SyntaxError
问题描述
我有一个简单的Python问题,我有大脑冻结。此代码段工作。但是当我用phoneNumber替换258 494-3929时,我得到以下错误:
#比较电话号码
phone_pattern ='^ \d {3}?\d {3} -\d {4} $'
#phoneNumber = str(请输入电话号码: ))
如果re.search(phone_pattern,258 494-3929):
print模式匹配
else:
printPattern doesn t匹配!
##################### #########################################
模式不匹配
请输入电话号码:258 494-3929
回溯(最近一次调用):
文件pattern_match.py,行16,in< module>
phoneNumber = str(input(Please enter a phone number:))
文件< string>,第1行
258 494-3929
^
语法错误:无效的语法

顺便说一下,我做了 import re
并在 \\\
解决方案您应该使用 raw_input
而不是 input
,并且您不必调用 str
,因为此函数返回一个字符串本身: / p>
phoneNumber = raw_input(请输入电话号码:)
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: "))
File "<string>", line 1
258 494-3929

SyntaxError: invalid syntax

By the way, I did import re
and tried using rstrip
in case of the \n
What else could I be missing?
解决方案 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: ")
