I have a list of different strings. I would like to find out a common regex expression (if any) for that list using Python.
For example, my list contains the following strings:
myList = ['This is first string', 'This is 2nd String', 'This is string 3', 'This is a final string']
Then I would like to programmatically determine if there is a regex expression which will match all the strings in the list. For instance, here the expression is something like 'This is *'. Will it be possible to do this programmatically?
use operator |
to join together each literal match. place inside ^(...)$
pattern = "^(" + "|".join(re.escape(item) for item in myStrings) + ")$"
它很简单, /\\'This is ([a-zA-Z0-9])*\\'/
/This is ([a-zA-Z0-9])*/
不需要引号/\\'This is ([a-zA-Z0-9])+\\'/
- 任何东西都必须在 This is 之后。
