in python, i'm trying to extract all time-ranges (of the form HHmmss-HHmmss) from a string. i'm using this python code.
text = "random text 0700-1300 random text 1830-2230 random 1231 text"
regex = "(.*(\d{4,10}-\d{4,10}))*.*"
match = re.search(regex, text)
this only returns 1830-2230
but i'd like to get 0700-1300
and 1830-2230
. in my application there may be zero or any number of time-ranges (within reason) in the text string. i'd appreciate any hints.

Try to use re.findall
to find all matches (Regex demo.):
import re
text = "random text 0700-1300 random text 1830-2230 random 1231 text"
pat = r"\b\d{4,10}-\d{4,10}\b"
for m in re.findall(pat, text):
print(m)
Prints:
0700-1300
1830-2230

Try this regex.
(\d{4}-\d{4})
All you need is pattern {four digts}minus{ four digits}. Other parts are not needed.
