Question

我想提取一行中关键字旁边的单词。注意：该关键字在该行中存在两次，我想在关键字旁边打印两个单词。

示例：

This is my first Python language and I like this language to the most.

所需输出:(需要以下格式language旁边的字词）

and    
to

Answer 1

re.findall具有零宽度正向后观（(?<=language )）以匹配language之前，然后使用\w+和print获取所需的子字符串sep='\n'获得所需的输出格式：

In [33]: s = 'This is my first Python language and I like this language to the most.'

In [34]: print(*re.findall(r'(?<=language )\w+', s), sep='\n')
and   
to

Answer 2

data = 'This is my first Python language and I like this language to the most.'


for i, word in enumerate(data.split()):
    if word == 'language':
        print(data.split()[i + 1])

Answer 3

text = "hola esto es una prueba donde esto busca la siguiente linea de esto"
brk = "esto"
for i, texto in enumerate(text.split(brk)):
  if i > 0:
    print( texto.split()[0] if len(texto.split()) > 0 else '')

现在你只需要改变文本和中断工作
