# 3 Approaches to find intersect of two lists:
# set two lists:
a = [1,2,3,4,5,6,7,8]
b = [8,7,4,3,100,200]
# the intersect c should be [3,4,7,8]
# Method 1:
c = list(set(a) & set(b))
print(c)
# Method 2:
c = list(filter(set(a).__contains__, b))
print(c)
# Method 3:
c = list(set(a).intersection(b))
