Python for loop start counter initialization

Question

for iteration in range(len(list) - 1):
  index = iteration +1 #This is the line which has no effect on the inner loop
  for index in range(len(list)):
    if list[it         


        

Answer 1

The for index in range(len(list)) loop executes the loop body with index first set to 0, then 1, then 2, etc. up to len(list) - 1. The previous value of index is ignored and overwritten. If you want index to start at iteration + 1, use the 2-argument form of range:

for index in range(iteration + 1, len(list)):
