Python re.search regex using or 条件

Question

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

>>> 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]

Answer 1

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.

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

or

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