What is the output?
>>> phrase = "hello mom"
>>> phrase upper()

The iutput would be nithing since nothing is printed out, how ever, the output of

>>> phrase = "hello mom"

>>> print(phrase.upper())

would be "HELLO MOM".

You would get the same results from this code,

>>> phrase = "hello mom"

>>> phrase = phrase.upper()

>>> print(phrase)

The answer is HELLO MOM
