Hi guys i just start to programming and im trying to get this right.

A = [['1','Jack','33'], ['2','Maria','23'], ['3','Christian','9'] ] 
B = [['1','Jack','33'], ['2','Maria','23'], ['3','Christian','9'], ['4','Denis','45'] ]

I want to check the array B[0] and print out just "4 Denis 45"

CodePudding user response：

I'm unsure what of you want. Is this it:

for lst in B:
    if lst not in A:
        print(" ".join(lst))

Output:

4 Denis 45
