One should be defensive and/or generalise (duck-typing) when writing functions. In this particular case - you can through any iterable to it and it behaves as expected. Little longer code now, lot of time saved on debugging in the future.

It seems that I cannot fully understand f-strings. I do exercises and little programs trying to update them by using f-strings, but now and then, I keep having some problems.

For instance, I wrote this little program:

# atbs_04_commaCode_01.py
#
# It works.
#

def commaCode(list1):
    print("'", end='')
    print(*list1[:-1], sep=', ', end=",")
    print(' and', list1[-1], end=".'\n\n")
          
spam1 = ['apples', 'bananas', 'tofu', 'cats']
commaCode(spam1)
eggs1 = ['bird', 'dolphin', 'whale', 'parrot', 'gorilla', 'dog']
commaCode(eggs1)
numbers1 = [1, 2, 3, 4, 5]
commaCode(numbers1)

that works and produces the following output:

Output:
'apples, bananas, tofu, and cats.'

'bird, dolphin, whale, parrot, gorilla, and dog.'

'1, 2, 3, 4, and 5.'

1) Is there a way to simplify the 3 lines of print with f-strings?
2) Is there a good tutorial FOR DUMMIES or FOR NEWBIES on all the details of f-strings?

I guess that I'm going to need much more time than expected sorting out what I had previously thought as an easy-peasy problem.
