доброго дня всем!
Я тут задачку решал. Опыт не большой, кажется код получился не совсем. Может расскажите как бы вы его написали или упростили. Спасибо заранее.

задача :

likes // must be “no one likes this”
likes // must be “Peter likes this”
likes // must be “Jacob and Alex like this”
likes // must be “Max, John and Mark like this”
likes // must be “Alex, Jacob and 2 others like this”

мое решение:

def likes(n):
if len(n) == 0:
return “no one likes this”
elif len(n) == 1:
a = (n + “ ” + “likes this”)
return(a)
elif len(n) == 2:
b = (n + “ ” + “and” + “ ” + n + “ ” + “like this”)
return b
elif len(n) == 3:
c = (n + “,” + “ ” + n + “ ” + “and” + “ ” + n + “ ” + “like this”)
return c
elif len(n) >= 4:
d = (n + “,” + “ ” + n + “ ” + “and” + “ ” + str(len(n)) + “ ” + “others like this”)
return d
