splitting lines, need to add element of same kind

[deanhystad]

Using a list you would need two lists, animals and animal counts.

to_app ='C:/02/All_an.txt'
 
animals = ['dog','cat','fish']  # Never use list as a variable name
counts = [0, 0, 0]
 
with open (to_app, 'r+') as app: 
    for line in app :
        line = line.strip()

        for index, animal in enumerate(animals):
            if animal in line:
                parts = line.split(",")
                count[index] += int(parts[2])
                break

for animal, count in zip(animals, counts):
    print(animal, count)

This code is hideous because there is no association between the count and the animal other than the position in the list. Since Python provides a datatype who's entire reason for existing is to provide a tight coupling, may as well use that.
