Implement the function printTwoLargest that inputs an arbitrary number of positive numbers from the user. The input of numbers stops when the first negative or zero value is entered by the user. The function then prints the two largest values entered by the user. If fewer than two distinct positive numbers are entered a message to that effect is printed instead of printing any numbers. Hint: Duplicates will cause problems. Try to make sure that you find a way to ignore them.

Answer:The function in Python is as follows:def printTwoLargest(): chk = 0 list1 = [] num = int(input("Enter: ")) while num &gt; 0: for i in list1: if i == num: chk+=1 break; if chk == 0: list1.append(num) chk = 0 num = int(input("Enter: ")) list1.sort() if len(list1) &gt;= 2: print("Largest:", list1[-1]) print("Second:", list1[-2]) else: print("Length of list must be at least 2")Explanation:This defines the functiondef printTwoLargest():This initializes a check variable to 0 chk = 0This initializes an empty list list1 = []This prompts the user for input num = int(input("Enter: "))The following loop is repeated until input is 0 or negative while num &gt; 0:The following for loop checks for duplicate for i in list1: if i == num: If duplicate is found chk+=1 The check variable is set to 1 break; And the for loop is exitedThe input is appended to the list if the check variable is 0 (i.e. no duplicate) if chk == 0: list1.append(num)This sets the check variable back to 0, for another input chk = 0This prompts the user for another input num = int(input("Enter: "))This sorts the list list1.sort()This prints the two largest if valid user input is 2 or more if len(list1) &gt;= 2: print("Largest:", list1[-1]) print("Second:", list1[-2])if otherwise, this prints that the length must be at least 2 else: print("Length of list must be at least 2")
