Jack is developing a program that calls for converting a list of words to uppercase. He tries out a strategy for this task in the Python shell, as follows:

listOfWords $=["$Apple$",$ "orange", "banana"$]$

for word in listOfWords:

word $=$ word.upper$()$

print$($listOfWords$)$

$[\text{'}$Apple$\text{'},$ 'orange', 'banana'$]$

Jack$$s strategy does not appear to produce the expected result. Determine the error and correct it$.$
