Automate the boring stuff with Python: Comma Code

Question

Currently working my way through this beginners book and have completed one of the practice projects \'Comma Code\' which asks the user to construct a program which:

Answer 1

As the function must work for all list values passed to it, including integers, therefore it should be able to return/print all values i.e. as str(). My fully working code looks like this:

spam = ['apples', 'bananas', 'tofu', 'cats', 2]

def commacode(words):

    x = len(words)

    if x == 1:
        print(str(words[0]))
    else:
        for i in range(x - 1):
            print((str(words[i]) + ','), end=' ')
        print(('and ' + str(words[-1])))

commacode(spam)
