Check Latest Date String

a = '2022-08-20T05:21:47.000Z'
b = '2022-08-22T05:21:47.000Z'
if a > b:
    print('a greater')
elif a < b:
    print('b greater')
else:
    print('a = b')
	
Output
b greater

Get 'b'List non matching numbers from 'a'List

a = [2,3,4,5,6,7,8,9,0]
b = [0,12,4,6,242,7,9]
for x in (x for x in b if x not in a):
    print(x)
	
Output

Compare Both Lists and Get matching values

a = [2,3,4,5,6,7,8,9,0]
xyz = [0,12,4,6,242,7,9]
for x in filter(lambda w: w in a, xyz):
  print (x)
