ShowMe is a simple set of extremely useful function decorators for Python. It allows you to view trace information, execution time, cputime, and function documentation.

Installation

To use showme, simply:

pip install showme

or, if you must:

easy_install showme

Usage

Print passed-in arguments and function calls. ::

@showme.trace
def complex_function(a, b, c, **kwargs):
    ...


>>> complex_function('alpha', 'beta', False, debug=True)
calling haystack.submodule.complex_function with 
   args: ({'a': 'alpha', 'b': 'beta', 'c': False},)
   kwargs: {'debug': True}

Print function execution time. ::

@showme.time
def some_function(a):
    ...

>>> some_function()
Execution speed of __main__.some_function:
0.000688076019287 seconds

Print function cpu-execution time. ::

@showme.cputime
def complex_function(a, b, c):
    ...

>>> complex_function()
CPU time for __main__.complex_function:
     3 function calls in 0.013 CPU seconds
