See previous about removing the redundant readlines()
line = line.strip()
if line in aisle_one:
first_run = "%s" % line + " - aisle one.\n"
The string formatting is redundant here since you assign a string to a
string
You could just dio:
first_run = line + " - aisle one.\n"
I can see that the variables first_run, second_run and third_run are
writing over themselves while looping, which is logical, but this is
not what I want. If I simply print them immediately instead of
storing
them as variables, all items will print, but not in the order I
wish.
So store the strings in a list then at the end print each list of
strings.
The ultimate goal of the program will be to sort the items based on
aisle locations. Is there an efficient way to do this?
You can sort the lists before printing...
I think I want some kind of incremental counter going on in the loop
to prevent them from overwriting themselves, or a way to store
multiple variables, but I'm not sure how to do that.
No need for counters, just append() to a list.
