find common elements in two arrays python code example
Example 1: find common elements in two lists python
list1 = [1,2,3,4,5,6]
list2 = [3, 5, 7, 9]
list(set(list1).intersection(list2))
Example 2: find number of common element in two python array
len([x for x in list1 if x in list2])
Example 3: python common elements in two arrays
import numpy as np
a = np.array([1,2,3,2,3,4,3,4,5,6])
b = np.array([7,2,10,2,7,4,9,4,9,8])
print(np.intersect1d(a,b))
Example 4: same elements of two sets in python
x = {2, 3, 5, 6}
y = {1, 2, 3, 4}
z = x.intersection(y)
