I saw pycallgraph on freshmeat today so spent a couple minutes playing with it. Initial impression is good and I’m looking forward to stretching its legs out soon. I through together a quick python script to see what pycallgraph is all about. Like most things in python is incredibily easy to use - with a couple lines of code you can add this into existing projects as well as new ones.

Here is the source for my test app:

#!/usr/bin/python
import pycallgraph

def aplusb(a,b):
    if a == 7:
        a = seven()
    return a   b

def aminusb(a,b):
    return a - b

def printTest(input):
    print 'Input is '   input

def seven():
    return 7

#################
pycallgraph.start_trace()

print 'starting script'
list = []
list.append( aplusb(7,4) )
print '7 - 4 = '   str( aminusb(seven(),4) )
printTest('this is a print test string')
print list
