如何在不区分大小写的情况下匹配字符串中的子字符串
问题描述:
我正在寻找Python中忽略大小写字符串的比较.
I'm looking for ignore case string comparison in Python.
我尝试过:
if line.find('mandy') >= 0:
但是忽略大小写没有成功.我需要在给定的文本文件中找到一组单词.我正在逐行读取文件.一行上的单词可以是 mandy , Mandy , MANDY 等.(我不想使用toupper
/
but no success for ignore case. I need to find a set of words in a given text file. I am reading the file line by line. The word on a line can be mandy, Mandy, MANDY, etc. (I don't want to use toupper
/tolower
, etc.).
我正在寻找下面与Perl代码等效的Python.
I'm looking for the Python equivalent of the Perl code below.
if ($line=~/^Mandy Pande:/i)

如果您不想使用str.lower()
,则可以使用正则表达式:
If you don't want to use str.lower()
, you can use a regular expression:
import re
if re.search('mandy', 'Mandy Pande', re.IGNORECASE):
# Is True
