问题

我想知道是否可以阻止Python 3中的输入被打印。

在上面的代码中，例如，如果我输入“236”，控制台会打印：

236
Even

我希望输出只是：

Even

谢谢！

我听说在Python 2.x中使用raw_input()函数可以实现这个。

英文:

I would like to know if it is possible to prevent an input from being printed in Python 3.

x = int(input())

def func(n):
    if n%2==0:
        print(&quot;Even&quot;)
    else:
        print(&quot;Odd&quot;)

func(x)

In the code above, for instance, if I input "236", the console prints:

236
Even

I would like the output to be just:

Even

Thanks!

I've heard this was possible in Python 2.x with the raw_input() function.

如果您键入输入，它将在Python看到之前通过终端显示在屏幕上。

要抑制这一点，请使用getpass，通常用于密码输入：

from getpass import getpass

x = int(getpass(prompt=''))

请注意，您仍然会看到换行符被打印，导致空行。

英文:

If you type an input, it's being displayed on screen by your terminal before Python even sees it.

To suppress this, use getpass, which is normally used for password input:

from getpass import getpass

x = int(getpass(prompt=&#39;&#39;))

Note that you still see the newline being printed, resulting in an empty line.
