Another Solution

if your txt file looks like this: mouse snake cat lizard wolf dog

you could reverse this file by simply using array indexing in python '''

contents=[]
def tail(contents,n):
    with open('file.txt') as file:
        for i in file.readlines():
            contents.append(i)

    for i in contents[:n:-1]:
        print(i)

tail(contents,-5)

result: dog wolf lizard cat
