Hi,

I've been using the following code to trace the execution of my programs:

import sys
import linecache
import random

def traceit(frame, event, arg):
    if event == "line":
        lineno = frame.f_lineno
        filename = frame.f_globals["__file__"]
        if filename == "<stdin>":
            filename = "traceit.py"
        if (filename.endswith(".pyc") or
            filename.endswith(".pyo")):
            filename = filename[:-1]
        name = frame.f_globals["__name__"]
        line = linecache.getline(filename, lineno)
        print "%s:%s:%s: %s" % (name,  lineno,frame.f_code.co_name , line.rstrip())
    return traceit


def main():
    print "In main"
    for i in range(5):
        print i, random.randrange(0, 10)
    print "Done."

sys.settrace(traceit)
main()

Using this code, or something like it, is it possible to report the values of certain function arguments? In other words, the above code tells me "which" functions were called and I would like to know "what" the corresponding values of the input variables for those function calls.

Thanks in advance.
