Do NOT use elif statement or nested if-else statement for this assignment. You should only need one single if-else statement at most (points will be deducted if more than one single if-else statement is used or the dictionary is changed). I need to build a program, luke.py, using the following dictionary: relations = {'Darth Vader':'father', 'Leia':'sister', 'Han':'brother in law', 'R2D2':'droid', 'Rey':'Padawan', 'Tatooine':'homeworld'} The program will take one argument, corresponding to one of the relations' keys. The program will print out the statement: "Luke, I am your x" Where x = the relationship. For example: If the argument is Leia, it should print "Luke, I am your sister" If the key is 'Darth Vader' it should instead print "No, I am your father" Also use sys.argv to test the function and no input() allowed and no additional libraries should be imported
