Python re.search正则表达式使用或条件

Hi Friends I'm trying to include "or |" condition in search pattern using re.search. Can someone help me how to achieve or condition as I'm not getting match. Below code works

嗨朋友我想包括“或|”使用re.search搜索模式中的条件。有人可以帮助我如何实现或条件，因为我没有得到匹配。下面的代码工作

>>> pattern = re.escape('apple.fruit[0]')
>>> sig = 'apple.fruit[0]'
>>> if re.search(pattern, sig):
...    print("matched")
...
matched 
>>> pattern = re.escape('apple.fruit[0] or vegi[0]')
>>> if re.search(pattern, sig):
...    print("matched")
...
>>>

I want to match above string "apple." followed by fruit[0] or vegi[0]

我想匹配上面的字符串“apple”。其次是水果[0]或vegi [0]

Regex or should be achieved through | operator and we don't inculde this inside re.escape. If you do so, then it would loose it's special meaning.

正则表达式还是应该通过|来实现运算符，我们不会在re.escape中包含这个内容。如果你这样做，那么它将失去它的特殊含义。

pattern = re.escape('apple.fruit[0]')+ '|' + re.escape('vegi[0]')

or

要么

pattern = r'apple\.fruit\[0\]|vegi\[0\]'
