trim a string of text, after a hyphen media in python-CodePudding

I just started with python, now I see myself needing the following, I have the following string:

1184-7380501-2023-183229

what i need is to trim this string and get only the following characters after the first hyphen. it should be as follows:

1184-738

how can i do this?

CodePudding user response：

s = "1184-7380501-2023-183229"

print(s[:8])

Or perhaps

import re

pattern = re.compile(r'^\d -...')
m = pattern.search(s)
print(m[0])

which accommodates variable length numeric prefixes.

CodePudding user response：

You could (you can do this a lot of different ways) use partition() and join()...

"".join([token[:3] if idx == 2 else token for idx, token in enumerate("1184-7380501-2023-183229".partition("-"))])
