如何在短語后獲得特定單詞？

Question

我正在處理一個包含文本的數據集，我想在文本中提取一個名稱。 所以它的 tweet_id，文本列，我想從推文文本中提取名稱。

text.startswith('This is ') and re.match(r'[A-Z].*', text.split()[2]):
    new_names.append(text.split()[2].strip(',').strip('.'))

這就是我用來在“this is”之后提取名稱的內容。

我想提取可能在文本中間的名稱，例如在“name is”和“named”之后，我該怎么做？

Answer 1

如果我理解你，這就是解決方案：

import re 

s = "This is Shahab .... my name is Shahab .... he is named Gholam"

names_regex = re.compile(r"[T|t]his\sis\s(\w+)|named\s(\w+)|name\sis\s(\w+)")
names = names_regex.findall(s)  

print(names)

Output：

[('Shahab', '', ''), ('', '', 'Shahab'), ('', 'Gholam', '')]

Answer 2

import re


text = "this pooch's name is Pepper. She's a sweet lovable monster. Although she has a lot of good qualities she also pees in the house and won't stop killing birds! Because of that we gave her an 8/10. Not bad."
m = re.search('(?<=name is\s)[A-Za-z]*', text, flags=re.IGNORECASE)
name = m.group(0)

print(name)
