[英]Does re.match(r'.*', string) have a limit?
#! /usr/bin/python3
import re
my_string = 'This is the string to test. It has several Capitalized words. My name is Robert, and I am learning pYthon.'
result = re.match(r'.*', my_string)
result.group(0)
print(result)
Forgive me for any issues I create posting this. 原谅我在发布此帖子时遇到的任何问题。 I am a total noob.
我完全是菜鸟。 I am trying to figure out why it is that when I run the above code, I get the follow results and not the full string.
我试图弄清楚为什么是这样,当我运行上述代码时,我得到了以下结果,而不是完整的字符串。
<_sre.SRE_Match object; span=(0, 108), match='This is the string to test. It has several Capit>
Thanks in Advance. 提前致谢。
You are printing result, not result.group(0). 您正在打印结果,而不是result.group(0)。 Just do
做就是了
print(result.group(0))
and you will see the whole string. 您将看到整个字符串。
This is a quirk of printing a regex match object. 这是打印正则表达式匹配对象的怪癖。 If you look in the
span
attribute of the object, the match goes from char 0 to the last char of your string (108), and if you print result[0]
as @sergio stated, you get the whole string 如果查看对象的
span
属性,则匹配从字符0到字符串的最后一个字符(108),并且如果按照@sergio的说明打印result[0]
,则会得到整个字符串
