""" Define the alter_the_list() function which is passed a string of
text and a list of words as parameters. The function removes any word
from the parameter list of words which is a separate word in the
parameter string of text.  The string of text should be converted to
lower case before you do any checking as the elements of the parameter
list of words are all in lower case.  Note that there is no punctuation
in the parameter string of text.  Note that each word in the parameter
list of words is unique, i.e., it occurs only once.  For example, the
following code:

word_list =  ["a", "is", "bus", "on", "the"]
alter_the_list("A bus station is where a bus stops  A train station is where a train stops  On my desk I have a work station", word_list)
print("1.", word_list)

word_list =  ["a", 'up', "you", "it", "on", "the", 'is']
alter_the_list("It is up to YOU", word_list)
print("2.", word_list)

word_list =  ["easy", "come", "go"]
alter_the_list("Easy come easy go go go", word_list)
print("3.", word_list)

word_list =  ["a", "is", "i", "on"]
alter_the_list("", word_list)
print("4.", word_list)

word_list =  ["a", "is", "i", "on", "the"]
alter_the_list("May your coffee be strong and your Monday be short", word_list)
print("5.", word_list)

prints:

1. ['the']
2. ['a', 'on', 'the']
3. []
4. ['a', 'is', 'i', 'on']
5. ['a', 'is', 'i', 'on', 'the']
