使用re.findall为您提供最简单的输出，并且适用于任意数量的匹配项。

sent = "this is a sentence 234225, and some 857307 other stuff, Time=72625, other stuff"

import re

print re.findall("Time=(\d+)", sent)
# ['72625']

If 

>>> st="this is a sentence 234225, and some 857307 other stuff, Time=72625, other stuff"

another way of doing it without regex is

>>> st.split("Time=")[-1].split()[0]
'72625'
