如何在python中使用正则表达式查找所有出现的单词

Question

如何使用正则表达式在以下字符串中找到所有出现的单词"good "

f = "good and obj is a  \good to look for it is good"

Answer 1

import re

regex = re.compile("good")
regex.findall("good and obj is a \good to look for it is good")

['good', 'good', 'good']

Answer 2

f = r"good and obj is a  \good to look for it is good"
m = re.findall('good ', f)

会给你：

['good ', 'good ']

在定义f时应该使用原始字符串，除非\应该与g一起使用

Answer 3

如果你想找到所有'好'的话

re.findll('good', f)

会奏效。 其他 你可以试试这个

import re
s = "good and obj is a \good to look for it is good"
s = re.sub(r'[^\/\s]good', '', s)
print re.findall(r'good', s)
