Question
(Eliminate duplicates) Write a function that returns a new list by eliminating the duplicate values in the list. Use the following function header:
def eliminateDuplicates(lst):
Write a test program that reads in a list of integers, invokes the function, and displays the result.
Here is the sample run of the program:
Enter ten numbers: 1 2 3 2 1 6 3 4 5 2
The distinct numbers are: 1 2 3 6 4 5
Answer
Eliminate duplicates Program code:
# Function to eliminate duplicate values from a list
def eliminateDuplicates(lst):
# Create an empty list to store distinct values
distinctNum = []
# Iterate over each element in the input list
for num in lst:
# Check if the element is not already in the distinctNum
if num not in distinctNum:
# Add the element to the distinctNum
distinctNum.append(num)
# Return the list with duplicate values eliminated
return distinctNum
# Test program
def main():
# Prompt the user to enter ten numbers separated by spaces
num = input("Enter ten numbers: ")
# Convert the input string to a list of numbers
numbers = [int(num) for num in num.split()]
# Call the eliminateDuplicates function to get the list with duplicate values eliminated
distinct_numbers = eliminateDuplicates(numbers)
# Display the distinct numbers
print("The distinct numbers are:", end=" ")
for number in distinct_numbers:
print(number, end=" ")
# Call the test program
main()
Executed Output:
Enter ten numbers: 1 2 3 2 1 6 3 4 5 2
The distinct numbers are: 1 2 3 6 4 5
