hgutils

hgutils

hgutils is a python package having a repository of various utilities which come handy during python project development.

Current Features

• Timer - A python class to measure and print execution time of python code running over loops and in series.
• Debugger - A python class to add print and or executable statements within the code and execute only if debugger mode is on.

Timer

This is a python class built to measure the execution time of python script.

Usage

Install hgutils to begin using timer class

$ pip install hgutils

Import hgutils in the python project and initiate timer class by assigning it to a variable while passing the project name in argument.

import hgutils
stopwatch = hgutils.timer("My Revolutionary Project")

Initiate the a new timer by calling start function and passing a name in argument. The new initiated timer will be child to current timer, which means current timer will continue to run and a new sub timer will be initiated.

stopwatch.start('New Timer')

To stop or end current timer simply call stop function. This function will end current timer, any parent timer(s) will keep on running. To end stop parent timer call the stop function again.

stopwatch.stop()

To get status of timers use print function.

stopwatch.print()

print functions have following arguments to fine tune the required details:

• units - millisesonds, seconds, minutes, hours, days and auto Default - auto. Defines the units in which time of execution will be printed. auto will automatically select the best units based on the calculated time of execution.
• verbose - 0, 1, 2 Default - 0. Determines the amount of information which will be printed.
  • 0: Time of only current timer will be printed
  • 1: Time of current timer and its parent will be printed
  • 2: Time of all the timers used in the project will be printed

Status of timer can also be printed while stoping the timer by passing argument print=True in stop function.

stopwatch.stop(print=True,verbose=1)

To reset the timer use reset function. This will delete all existing timers and initiate a new timer for project.

stopwatch.reset()

Examples

Here's a sample python project implemented using timer utility.

import hgutils
import time

print("Using timer utility available in hgutils")
stopwatch = hgutils.timer("hgutils timer sample project")
time.sleep(2)
stopwatch.start("Top Level Timer")
for i in range(4):
    stopwatch.start("i="+str(i))
    time.sleep(1)    
    if i==2:
        for j in range(5):
            stopwatch.start("j="+str(j))
            time.sleep(.04)
            stopwatch.stop(print=True,verbose=1)
    stopwatch.stop(print=True,verbose=1)
stopwatch.stop(print=True,verbose=1)
stopwatch.print(verbose=2)

	 Top Level Timer - 3.24 seconds*
		 i=2 - 1.23 seconds
	 Top Level Timer - 4.24 seconds*
		 i=3 - 1.01 seconds
 hgutils timer sample project - 6.25 seconds*
	 Top Level Timer - 4.24 seconds
 hgutils timer sample project - 6.25 seconds*
	 Top Level Timer - 4.24 seconds
		 i=0 - 1.01 seconds

			 j=4 - 41.47 milliseconds
		 i=3 - 1.01 seconds

Debugger

This is A python class to add print and or executable statements within the code and execute only if debugger mode is on.

Usage

Install hgutils to begin using timer class

$ pip install hgutils

Import hgutils in the python project and initiate debugger class by assigning it to a variable while passing the project name in argument.

import hgutils
dbug = hgutils.debugger("My Revolutionary Project's Debugger")

Set debugging mode ON by calling debugging_on function and turn it OFF by calling debugging_off function. By default debugging mode is OFF.

dbug.debugging_on()
dbug.debugging_off()

Use execute() function to add printable / executable statements. These will be active only when debugger mode is ON.

dbug.execute(title='Statement Title', print='This will be printed if debugger mode is ON')

execute functions have following arguments to be used as per requirements:

• title - title for current execution Default - None. This is the first line which will be printed when statement is executed in debugger mode ON. If None nothing will be printed.
• print - Statement to be printed Default - None. Statement which will be printed after printing title.
• execute - function to be executed Default - None. Function which will be executed. Note pass the function object here and not the executed object.
• args - arguments to the executable function Default - None. These are arguments which will be passed to the executable function.
• print_signature - flag to determine if the signature will be printed towards the end Default - False
