Cannot print a specific number from a sublist within a list

Question

I want to be able to print the 3rd number with in a list of sublist. I am okay with interacting through the list and sublist, but unsure with how i can print the 3rd number of each sublist. for example [[1,2,3,4][1,2,3,4][,1,2,3,4][1,2,3,4]] i was to achieve 3,3,3,3

I have manage this so far, being able to print out all numbers with the sublists

def Contact(num):<br/>
    for i in range(len(num)):<br/>
        for j in range(len(num[i])):<br/>
                print(num[i][j])

Contact([[1,2,3,4][1,2,3,4][,1,2,3,4][1,2,3,4]])

Same as you have, but instead of an inner loop just print the 3rd element: for sublist in list: print sublist[2] — Jacob H, Jun 12 '16 at 16:27
you are missing a comma between the first, and second and third sublists — joel goldstick, Jun 12 '16 at 16:32

try this here http://pythonfiddle.com/

def Contact( mainlist ):
    for sublist in mainlist:
        print( sublist[2] ) # accessing third element

Contact( [ [ 1,2,3,4 ], [ 1,2,3,4 ], [ 1,2,3,4 ], [ 1,2,3,4 ] ] )
