get-profile 0.0.2

Quickly profile your code with a single line of code.

get-profile

A simple library to inject the most profiling bang-for-buck into a single line of code (decorator).

I.E.

import time

from get_profile import get_profile


def your_function_a():
    time.sleep(1)

def your_function_b():
    time.sleep(2)


@get_profile
def your_program():
    your_function_a()
    your_function_b()


if __name__ == '__main__':
    your_program()

Would print something like this after your program has run:

Profiling results for "your_program":

Installation

get-profile can be installed with pip:

$ pip install get-profile

Decorator Parameters

Release 0.0.2 supports the following parameters for the get_profile decorator:

get_profile(

# topn limits the table to only the top n rows
top_n: int = 10,

# only_my_functions = True will filter out functions whose 
# "func" field contains the regex pattern: 
# r"/python[0-9]+\.[0-9]+/|<.*>",
# (a hacky way to limit the output to just your own functions)
only_my_functions: bool = False,  

# sort_by is the column you would like to sort by (descending)
sort_by: str = "tottime -r",

# min_col is the column you would like to filter by (min_val)
min_col: str = "tottime -r",

# min_val is the minimum value for the min_col
min_val: float = 0.005,

# output_width is the width in chars of the output table
output_width: int = 150,

# toggles whether or not the "calees" column is printed
callees: bool = True,

)
