Thanks! Using that I tried it out for cDNA, and I've gotten really close but I haven't been quite able to hit the desired effect with modifying the line. 

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 = 2

# 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 * N_cDNA
    target = "{}".format(wells)
    targets.append(target)
   
  transfer(
           6, 
           mm,
           targets
         )
 
 
for i, cd in enumerate(cDNA_sources):
  #list of targets for cDNA
  targets =
   
  # loop over the number of mastermixes then loop over the number of tests
  for j in range(N_mm):
    for k in range(replicates):
      wells = i + 1 + j * replicates + k
      target = "{}".format(wells)
      targets.append(target)
   
  transfer(
             4, 
             cd,
             targets
           )

For the output I get close - but not quite

Transfering     6ul from A1 to ['1', '2', '3', '4']
Transfering     6ul from A2 to ['5', '6', '7', '8']
Transfering     4ul from B1 to ['1', '2', '3', '4']
Transfering     4ul from B2 to ['2', '3', '4', '5']

The numbers repeat except for one. I don't think the equation needs to be shifted (adding numbers) but I was wondering what I should consider multiplying if that makes sense?

Do you know where I went wrong?
