I need to write a program that will check the numbers that a user enters. If the user enters a number more than once then it will skip over it and print out only numbers that the user entered once.
I was playing around with this:
def single_element():
numbers = []
numbers = input("Enter some numbers: ").split()
for i in numbers:
if i in numbers:
i + 1 #I was trying to find a way to skip over the number here.
print(numbers)
You can build a set to just print unique numbers:
numbers = input("Enter some numbers: ").split()
print set(numbers)
Use a set. They are iterables, like lists, and can easily be converted back and forth. However, sets do not contain duplicate values.
def single_element():
numbers = list(set(input("Enter some numbers: ").split()))
print(numbers)
In this function, you get the input numbers as a list and convert them to a set, which will remove duplicates, and then convert back to a list.
Note: sets are not guaranteed to keep the same order like lists.
