Python输入中断if语句

Question

我正在使用Python 3.9.12。我正在做一个程序，你在你的国家周围输入的边界数目。如果在您的国家周围没有任何边框，则打印(无边界)，elif有一个国家打印(只有一个边框)其他打印(超过一个边框)。

问题:我无法让输入打印正确的输出。如果我注释掉输入，然后像这样在number_of_neighbours中插入数字，它就能工作了：

number_of_neighbours = 0
number_of_neighbours = int(number_of_neighbours) 
if number_of_neighbours  == 0:
    print('No borders')
elif number_of_neighbours  == 1:
    print('Only 1 border!')
else: 
    print('More than 1 border!')

但是我想像这样使用输入，但是它不起作用。我读过和看过的东西，我的脸是蓝色的，但我错过了一件事，我不知道它会是什么。我已经为此工作了两天了。

number_of_neighbours = 0
int(input('How many neighbouring countries does your country have?'))
number_of_neighbours = int(number_of_neighbours) 
if number_of_neighbours  == 0:
    print('No borders')
elif number_of_neighbours  == 1:
    print('Only 1 border!')
else: 
    print('More than 1 border!')

任何帮助和解释都将不胜感激。

Answer 1

number_of_neighbours = int(input('How many neighbouring countries does your country have?'))
if number_of_neighbours  == 0:
    print('No borders')
elif number_of_neighbours  == 1:
    print('Only 1 border!')
else: 
    print('More than 1 border!')

您需要将输入赋值给变量。
