Python Regex Search string for all substrings having one or more numbers -


in python, have following string:

"fish 14~ reel 14 rod b14"

i want use regex run through loop , return location of each substring having 1 or more numbers in it. ex.:

 ():      print location of substring

my expect output be:

5 14 21

please help, thanks.

answer: ok tested of following , work. 1 fastest? drum roll.... in order fastest slowest: 1) perreal - 9.7ms 2) jon - 10.5ms 3) m.buettner - 12.3ms 4) upasana - 25.6ms

thanks of python geniuses. there solution didn't test it. various other reasons chose jon's method program.

something like:

s =  "fish 14~ reel 14 rod b14"  import re  words = re.finditer('\s+', s) has_digits = re.compile(r'\d').search print [word.start() word in words if has_digits(word.group())] # [5, 14, 21]

so, find indices of starts of words, check each word see if it's got digits in it...

if indeed last entry should 22 instead of 21, have answer in possible duplicate...
