How to find match items from two lists? [duplicate]

Answer 1

Use sets:

set(data1) & set(data2)

The & operator means "give me the intersection of these two sets"; alternatively you can use the .intersection method:

set(data1).intersection(data2)

Answer 2

>>> [ name for name in data1 if name in data2 ]
['name3']

Answer 3

nf = [x for x in data1 if x in data2]
nf

would return the common item in both lists

Answer 4

For a in data1:
    for b in data2:
        if a==b:
        print(a)

That's one way to do it, not the best way though
