Noemi Cabrera - Module Four Lab

# Noemi Cabrera # 1 October 2021 # In this lab, I practiced using if/else Conditionals along with elif statement, casting from one data type to # another, gathering numeric input using type casting, and performing subtraction, multiplication and # division operations in code # I did not have any difficulties in this lab

# [In the defined function, the user enters input on the favorite rainbow color. The function returns the letter # and color that matches with the user input. If the letter is not on the list, "no match" will print.] # make the code above into a function rainbow_color() that has a string parameter, # get input and call the function def rainbow_color(color): fav_color= input("Enter the first letter of your favorite rainbow color (ROYGBIV): ").upper() if fav_color == "R": return("R = Red") elif fav_color == "O": return("O = Orange") elif fav_color == "Y": return("Y = Yellow") elif fav_color == "G": return("G = Green") elif fav_color == "B": return("B = Blue") elif fav_color == "I": return("I = Indigo") elif fav_color == "V": return("V = Violet") else: return("no match") print("Your color:") print(rainbow_color("O"))

# [ This code represents an addition calculator.

# [ This code represents a multiplying calculator.

# [ The numbers are stored in variables. If the small number is equal to 0, the result"0" will display. # But if it's not 0, the division between the two will display. ] # Divide a larger number by a smaller number and print the integer part of the result # don't divide by zero! if a zero is input make the result zero # [ To cast the answer as integer the int() function is used.] cast the answer to an integer to cut # off the decimals and print the result l_num = 12 s_num = 6 if s_num == 0: print(0) else: division = l_num / s_num print(int(division))
