This article mainly introduces whether a python list contains all elements of another list. It has a certain reference value. Now I share it with you. Friends in need can refer to it
As shown below:
#!/usr/bin/env python # coding: utf-8 a = [1, 2, 3, 4, 5] b = [3, 4, 5] d = [False for c in b if c not in a] if d: print "a不包含b的所有元素" else: print "a包含b的所有元素"
You can also consider converting to a set and then finding the intersection to see if it is equal to the smaller set.
