Question

我希望找到以ing结尾的单词并打印它们，我当前的代码打印出而不是单词。

#match all words ending in ing
import re
expression = input("please enter an expression: ")
print(re.findall(r'\b\w+(ing\b)', expression))

所以如果我们输入一个表达式：sharing all the information you are hearing

我希望['sharing', 'hearing']打印出来相反，我打印出['ing', 'ing']

有没有快速解决方法？

Answer 1

您的捕获分组错误请尝试以下操作：

>>> s="sharing all the information you are hearing"
>>> re.findall(r'\b(\w+ing)\b',s)
['sharing', 'hearing']

您还可以在列表解析中使用str.endswith方法：

>>> [w for w in s.split() if w.endswith('ing')]
['sharing', 'hearing']

Answer 2

圆括号“捕获”字符串中的文本。您有'(ing\b)'，因此只会捕获ing。移动左括号，使其包含您想要的整个字符串：r'\b(\w+ing)\b'。看看是否有帮助。

Answer 3

尝试一下。会的！

import json,tempfile
config = {"A":[1,2], "B":"Super"}
tfile = tempfile.NamedTemporaryFile(mode="w+")
json.dump(config, tfile)
tfile.flush()
print(tfile.name)

Answer 4

sentence = 'sharing all the information you are hearing'
# spit so we have list of words from sentence
words =  sentence.split(' ')


ending_with('ing',words)

def ending_with(ending, words):
    # loop through words
    for word in words:
        # if word has ends with ending
        if word.endswith(ending):
            # print
            print word
