(Duplicate word removal) Write a function that reads in a text and determines the number of unique words in alphabetical order.

• Read in a text, for example Let it be let it be, use string.split(separator) function to break it into a list of strings/words by the specified separator (white space).
• Displays in alphabetical order only the unique words. Treat uppercase and lowercase letters the same (as lowercase).
• Demonstrate how to use string.split(separator) ( If separator not provided, then any white space is a separator).

text = Let it be let it be

myList = text.split( ) # myList is a list: [Let, it, be, let, it, be]

• The function should use a set to get the unique words in the list.
• Print out the unique words and the number of unique words
• Test your function with other text/sentences
