# get the spelling list as a list of words
text = url.get_contents( SPELLING_LIST_URL )
spellings = text.split() # Get a list of correctly spelled words from
# the web file - we do this once! It's just a huge list of correctly
# spelled words.
# print( spellings )

# get the user text as a list of words
reply = input( "Enter text: " )
reply = reply.lower()
words = reply.split()

# Every word in spellings list is lowercase.
# We want to check if each word in our text (user input)
# in the words list is in spellings. Print it out if it's not in there!

# consider the words one by one -- determine whether current word is misspelled.
for word in words:
    if (word not in spellings):
        print(word)
    else:
        pass
    # We need to find out if word is misspelled

    # Remember some commonly used test expression things include
    # >=, <=, ==, in, not in, and, or, etc. Could one of these help?
    # if ( a in b ) - checks if a is in the sequence b (can be string or list)

    # Alternate Way:
    # if ( word in spellings ):
    #     pass
    # else: # if word not in spellings
    #     print( word )

# all done
