Hi,

how can I extract 2 integers from a string in python?

for example, my source string is this:
Total size: 173233 (371587)

I want to extract the integer 173233 and 371587 from that soource
string, how can I do that?

Use split() to split the string into four strings, using spaces as
separators, then use int() to convert the resulting strings that
interest you.

a, b, c, d = 'Total size: 173233 (371857)'.split()
first_int, second_int = int(c), int(d[1:-1])
first_int 173233
second_int

371857

E.g.:

#v+

import re
re.findall(r'\d+', 'Total size: 173233 (371587)') ['173233', '371587']

#v-

a, b, c, d = 'Total size: 173233 (371857)'.split()
first_int, second_int = int(c), int(d[1:-1])

int(d[1:-1]) can be replaced by d.strip("()"), which may or
may not be clearer in intent.

Nicely expressed.

People doing a lot of report-scraping might also want to
consider one of the scanf implementations for Python.
<URL: http://hkn.eecs.berkeley.edu/~dyoo/python/scanf/ >
has an example.
