[Tutor] Searching a text file's contents and comparing them toa list

[Eric Hamiter]

Follow-up question: My code is now this:

aisle_one = ["chips", "bread", "pretzels", "magazines"]
aisle_two = ["juice", "ice cream"]
aisle_three = ["asparagus"]

def find_groceries():
    grocery_list = open("grocery_list.txt", "r")
    for line in grocery_list.readlines():
        line = line.strip()
        if line in aisle_one:
            first_run = "%s" % line + " - aisle one.\n"
        elif line in aisle_two:
            second_run = "%s" % line + " - aisle two.\n"
        elif line in aisle_three:
            third_run = "%s" % line + " - aisle three.\n"
        else:
            out_of_luck = "%s" % line
    print first_run, second_run, third_run
    print "I couldn't find any %s. Add it to the database. \n" % out_of_luck
    grocery_list.close()

find_groceries()


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.
The ultimate goal of the program will be to sort the items based on
aisle locations. Is there an efficient way to do this?

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.

Thanks for any ideas. This list and all its participants are super
helpful-- I'm very appreciative.
