code_timer

Simple python timer to use for single lines of code, or entire functions/classes

New Features!

• Use code_timer.Timer as a class, context manager, decorator
  • Offers the most versatility and flexibility for your needs
• Use separate code_timer.timer decorator
• Use code_timer.timeit decorator to measure the time to run the same function multiple times
  • Useful when comparing the efficiency of one runtime vs another
  • By default, will run the function 10,000 times. The number of runs is configurable
  • DO NOT USE THIS FOR RECURSIVE FUNCTIONS!!
• Logger allowing you to set the streaming level or hide the logging entirely

Basic Usage

code_timer.Timer

1. As a class:

   t = Timer(name="class")
   t.start()
   # Do something
   t.stop()

2. As a context manager:

• Useful when trying to time a recursive function

  with Timer(name="context manager") as t:
      # Do something
  print(f"Elapsed time: {t.elapsed_time}")

3. As a decorator:

   @Timer(name="decorator")
   def stuff():
       # Do something

code_timer.timer

1. Without braces

   @timer
   def your_func():
       # Do something

2. With braces

   @timer(name="my_timer")
   def your_func():
       # Do something

code_timer.timeit

• Time is reported at logging level: logging.INFO
• The following assumes the standard formatting for the code_timer logger

1. Default

   • will repeat the function 10,000 times and report the fastest three runs

   @timeit
   def your_func():
       # Do something

   • Output: 2020-03-12 21:56:46: code_timer.INFO - Best 3 of 10000 for your_func: 0.2200 ms; 0.2220 ms; 0.2232 ms

2. Pass in the number of times to repeat

   @timeit(num_repeats=50)
   def your_func():
       # Do something

   • Output: 2020-03-12 21:56:46: code_timer.INFO - Best 3 of 50 for your_func: 0.2200 ms; 0.2220 ms; 0.2232 ms
