Thank you for the dictionary. It was able to translate wells (A1) to their number (1) but I had trouble adding it into my code to convert the A1 coordinates to numbers. So, I tried out another thing. 

I thought that maybe I could combine the rows/columns and create just one 'wells' as the target like this:

def transfer(p_amount, p_source, p_target):
 print("Transfering {:>5}ul from {} to {}".format(p_amount, p_source, p_target))
 
# number of mastermixes
N_mm = 3

# number of cDNA samples 
N_cDNA = 2
# number of tests to run on each sample
replicates = 2

mastermix_sources = list("A{}".format(j+1) for j in range(N_mm))
cDNA_sources = list("B{}".format(j+1) for j in range(N_cDNA))
 
for i, mm in enumerate(mastermix_sources):
  #list of targets for mastermix
  targets =
  for j in range(N_cDNA * replicates):
    wells = j + 1 + i*replicates 
    target = "{}".format(wells)
    targets.append(target)
   
  transfer(
           6, 
           mm,
           targets
         )
 

I did some fiddling around and it spits out the right numbers in ascending order (for the first half - haven't touched the cDNA portion yet) but it repeats numbers. Is there a way to restrict repeating numbers. I tried some if commands but I kept getting syntax errors. 

Here's the output-

Transfering     6ul from A1 to ['1', '2', '3', '4']
Transfering     6ul from A2 to ['3', '4', '5', '6']
Transfering     6ul from A3 to ['5', '6', '7', '8']
