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

有一个简单/单行python等同于R的gsub函数吗?

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

1 个解决方案

#1

For a a string:

对于一个字符串:

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

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

由于您将问题更新为字符串列表,因此可以使用列表推导。

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