最简单的 python 相当于 R 的 gsub [英] simplest python equivalent to R's gsub

问题描述

是否有一个简单的/一行 Python 等价于 R 的 gsub 函数?

Is there a simple/one-line python equivalent to R's gsub function?

strings = c("Important text,      !Comment that could be removed", "Other String")
gsub("(,[ ]*!.*)$", "", strings) 
# [1] "Important text" "Other String"  

推荐答案

对于字符串:

import re
string = "Important text,      !Comment that could be removed"
re.sub("(,[ ]*!.*)$", "", string)

由于您将问题更新为字符串列表，因此您可以使用列表推导式.

Since you updated your question to be a list of strings, you can use a list comprehension.

import re
strings = ["Important text,      !Comment that could be removed", "Other String"]
[re.sub("(,[ ]*!.*)$", "", x) for x in strings]
