how to time functions in python code example

Example 1: python time a funciton

import time

start = time.time()
print("hello")
end = time.time()
print(end - start)

Example 2: python: measure time code

import time

# Calculate the power of two for a defined range of number
def power_two(my_range):
    return [x**2 for x in range(my_range)]
 
# Measure time
def measure_time(func):
    start = time.time()
    func()               # any specific function to measure
    end = time.time()
    print(end - start)  
    
measure_time(lambda: power_two(10000000)) # lambda permits to pass the argument of our function

Example 3: time in python

import time
thistime = time.time()
# Here's an idea!
def CountTime():
  while(True):
    time.sleep(1)
    print(thistime)
CountTime()

Example 4: timer in python

timer = threading.Timer(interval, function, args = None, kwargs = None)
timer.start()

Example 5: time a function python

Proper answer to timing a loop over a function multiple times
import timeit
timeit.timeit('func_to_time()',globals=globals(),number=1000)

Example 6: time python

#import time module:
import time
#module has various attributes: 
dir(time)
[..., 'localtime', 'mktime', 'sleep', 'sleep_ms', 'sleep_us', 'ticks_add', 'ticks_cpu', 'ticks_diff', 'ticks_ms', 'ticks_us', 'time']

#default expression is in seconds with zero being start of runtime
secFromStart = time.time()
