time a function python

1import time

3start = time.time()
4print("hello")
5end = time.time()
6print(end - start)

1import time

3# Calculate the power of two for a defined range of number
4def power_two(my_range):
5    return [x**2 for x in range(my_range)]
6 
7# Measure time
8def measure_time(func):
9    start = time.time()
10    func()               # any specific function to measure
11    end = time.time()
12    print(end - start)  
13    
14measure_time(lambda: power_two(10000000)) # lambda permits to pass the argument of our function

2seconds = time.time()
3print("Seconds since epoch =", seconds)
