Python 

Statement
Create letter combinations of that consist of elements of listl and list2.
Use your pseudocode and'or diagram. Check your output
Requirements
• Create a function that will combine the letters from lists 1 and 2
• Letter combinations will be appended to the list letter_combinations
• If a letter combination already exists in letter_combinations, then it must be saved to the
list repeated_combinations
• The lists letter_combinations and repeated_combinations must be lists of Tuples
• Each tuple will be in (list1letter, list21letter) format
Hints
• Review the videos. Have them open while you code if you need to.
• For loops are useful to iterate through items in a list
• The IN operator is useful to verify whether an item exists in a list
• Use the append) method
• Your function should return 2 values: letter_combinations and repeated_combinations
• Sometimes a well-placed print statement will help you know what you're doing wrong
• You can change the content of listl and lits2 for testing purposes, but YOU MUST USE
THE ORIGINAL VALUES OF THE LISTS IN ORDER FOR YOUR ALGORITHM TO
BE GRADED PROPERLY
list1 = ['A', 'B', 'C', 'E', 'J']
list2 = ['A', 'C', 'D', 'B', 'E', 'Z', 'B', 'A', 'F', 'B', 'H', 'A']
letter_combinations - []
repeated_combinations = (]
