Mastering Python Scripting for System Administrators

The cProfile module

As discussed previously, profiling means measuring the execution time of a program. We are going to use the cProfile Python module for profiling a program.

Now, we will write a cprof_example.py script and write the following code in it:

mul_value = 0def mul_numbers( num1, num2 ):            mul_value = num1 * num2;            print ("Local Value: ", mul_value)            return mul_valuemul_numbers( 58, 77 )print ("Global Value: ", mul_value)

Run the program and you will see the output as follows:

student@ubuntu:~$ python3 -m cProfile cprof_example.pyLocal Value:  4466Global Value:  0         6 function calls in 0.000 seconds   Ordered by: standard name    ncalls  tottime  percall  cumtime  percall filename:lineno(function) 1 0.000 0.000 0.000 0.000 cprof_example.py:1(<module>) ...
