Python 检查输入中的数字

Question

我需要编写一个程序来检查用户输入的数字。如果用户多次输入一个数字，那么它将跳过该数字并仅打印用户输入一次的数字。

我正在玩这个:

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)

Answer 1

您可以构建一个集合来仅打印唯一的数字:

numbers = input("Enter some numbers: ").split()
print set(numbers)
