How to get chromosome coordinates from a string using RegEx in Python

def get_chr_coordinates_from_string(s):
	'''
	Returns chromosome coordinates from a given string.
	Coordinates have to be in "chr0:0000-0000" style!
	'''
	import re
	regex_for_chr       = re.compile('chr[0-9a-zA-Z_]*:')
	regex_for_start_end = re.compile('chr[0-9a-zA-Z_]*:[0-9]+-[0-9]+')
	chr  	   = re.search(regex_for_chr, s).group().replace(':', '')
	start, end = re.search(regex_for_start_end, s).group().split(':')[1].split('-')
	return(chr, start, end)

Example:

>>> s=">hg19_refGene_NM_012147 range=chr4:191008763-191010142 5'pad=0 3'pad=0 strand=+ repeatMasking=none"
>>> get_chr_coordinates_from_string(s)
('chr4', '191008763', '191010142')
