Summary: misbehaviour with map / lambda / isdigit()

Initial Comment:
This code causes "0".isdigit() to incorrectly report
False. Also apparent on RHEL with Python 2.2.3.

This is not a bug: the expression ("0".isdigit() and
int("0")) is False, not True as you expected.
What you can do is:
strlist = ['0', '1', '42', 'foo']
intlist = [ int(x) for x in strlist if x.isdigit() ]
