I have three 3d list below. I would like to find a match in the same row as B & C that matches A then return only the matching values. For example, if A finds a match in B in row 3 also has to be the same row in C. Here is my 3d list below. A = [[11, 27, 41, 42], [7, 26, 34, 36], [8,22, 24, 38, 42]] B = [[11, 42], [11, 32], [7, 14], [11, 17, 21], [21, 38], [11, 42,45]] C = [[15, 16, 21, 27, 38, 44], [34, 39, 42], [20, 21, 35, 36, 49], [2, 12, 22, 24, 30], [21, 22, 27, 31, 42], [1, 5, 8, 27, 32, 38]] I have tried this code below, but it's doesn't work the way I would like. match = [] for e in A: for f in B: for g in C: set_e = set(e) set_f = set(f) set_g = set(g) h = set_i & set_j | set_i & set_z if len(h) > 0: match.append(list(h)) print(match) I would like my result to be like this. The matching values in the same row as B & C match = [[11, 42, 27], # 11,42 in A & B and 27 in A & C in row 0 [11, 42], # 11 in A & B and 42 in A & C in row 1 [11, 42, 27], # 11,42 in A & B and 27 in A & C in row 5 [[42, 38], # 42 in A & B and 38 in A & C in row 0 [38, 42, 22], # 38 in A & B and 42, 22 in A & C in row 4 [42, 38, 8]] # 42 in A & B and 38 in A & C in row 5 Continue reading...
