python timer in seconds passed code example

Example 1: python time a funciton

import time

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

Example 2: How to check how much time elapsed Python

import time
t0= time.clock()
print("Hello")
t1 = time.clock() - t0
print("Time elapsed: ", t1) # CPU seconds elapsed (floating point)

Example 3: 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
