pydb (http://bashdb.sourceforge.net) has a linetrace option sort of
like what's done in POSIX shells.
Here's an example:
#!/usr/bin/python
"""Towers of Hanoi"""
import sys,os
def hanoi(n,a,b,c):
if n-1 > 0:
hanoi(n-1, a, c, b)
print "Move disk %s to %s" % (a, b)
if n-1 > 0:
hanoi(n-1, c, b, a)
i_args=len(sys.argv)
if i_args != 1 and i_args != 2:
print "*** Need number of disks or no parameter"
sys.exit(1)
n=3
if i_args > 1:
try:
n = int(sys.argv[1])
except ValueError, msg:
print "** Expecting an integer, got: %s" % repr(sys.argv[1])
sys.exit(2)
if n < 1 or n > 100:
print "*** number of disks should be between 1 and 100"
sys.exit(2)
hanoi(n, "a", "b", "c")
