import numpy as np
import time
import sys
let's declare the size
Size = 100000
Creating two lists
list1 = range(Size)
list2 = range(Size)
Creating two NumPy arrays
arr1 = np.arange(Size)
arr2 = np.arange(Size)
Calculating time for Python list
start = time.time()
result = [(x ,y) for x, y in zip(list1, list2)]
print("Time for Python List in msec: ", (time.time() - start) * 1000)
Calculating time for NumPy array
start = time.time()
result = arr1 ,arr2
print("Time for NumPy array in msec: ", (time.time()- start) * 1000)
print("\nThis means NumPy array is faster than Python List")
