Question

Write a Python program prints out the unique elements of a list lst in a sorted manner (i.e it removes duplicates from the list). For example, if list is [10,20,30,20,10,50,60,40,80,50,40], the output should be [10, 20, 30, 40, 50, 60, 80].?

Answer 1

lst = eval(input("Enter a list: "))

# go through all the elements of the list and create a list without duplicates
result = []  # create an empty list as result
for item in lst:  # go through each item in list
    if item not in result:  # if that item is not already in result list
        result.append(item)  # then add it to the result list
result.sort()  # sort the list
print(result)  # print the list
