Python- re.search() // Match start and end but do not include either in match result-CodePudding

My intention is to get all inbetween 'start' and 'end' variables. Currently struggling to understand how to apply the filters to get group excluding the start and end criteria.

start = 'melons'
end = 'strawberry'
s = 'banana apples melons cucumber strawberry grapes'

r = re.search('', s)

print(r.group(1)) 
#print =  cucumber

Can be achieved with below approach:

import re
start = 'melons'
end = 'strawberry'
s = 'banana apples melons cucumber strawberry grapes'

r = re.search(rf'{start}(.*?){end}', s)

print(r.group(1))

Output:

 cucumber

If you're starting off with Regex, then I recommend you use this tool. It's very useful and can help you write your own regex statements. It also will compile your statement to a language of your choice.

In the meantime, you can use a statement like melons(.*)strawberry:

import re

regex = r"melons(.*)strawberry"

matches = re.search(regex, "banana apples melons cucumber strawberry grapes")

print(matches.groups()[0])
#  cucumber
