When you press Control C, a <code>KeyboardInterrupt</code> exception is thrown. If it isn't stopping the code, the best thing to do is to add a <code>try</code> statement into your code which catches <code>KeyboardInterrupt</code>

<pre><code>try:
 ....

except KeyboardInterrupt:
 exit()
</code></pre>

The code is just off the top of my head so sorry if something is wrong. 

EDIT: <code>Ctrl Break</code> or on some keyboards <code>Ctrl Pause</code> instantly stops python code apparently.

This is a bug that recently appeared in Windows 10 Insider build 15002.

A work around is to change the Mapped Keys from Ctrl C to something like Ctrl K 

If you are not familar how to do this, You can look up or at <code>stty -a</code>

You can run this command on each bash session that will map your Terminate to Ctrl + K

<pre><code>stty intr \^k
</code></pre>

As a TEMP solution you could include this in your Bashrc so it is executed on each new session 

This bug has been reported already on Github #1569

<blockquote>
When I used to press Ctrl-C, python was quit normally without any output.
</blockquote>
I really don't remember when I can quit python with <code>Ctrl + C</code>. In my memory, <code>Ctrl + C</code> always give me <code>KeyboardInterrupt</code>.
<hr />
I also counldn't find an answer explaining why <code>Ctrl + C</code> can't quit the python in shell. FYI, <code>Ctrl + D</code> and <code>Ctrl + \</code> can quit python for different reasons. See @Gilles's answer here. <a href="https://superuser.com/questions/169051/whats-the-difference-between-c-and-d-for-unix-mac-os-x-terminal">https://superuser.com/questions/169051/whats-the-difference-between-c-and-d-for-unix-mac-os-x-terminal</a>
<hr />
But I think how to handle <code>Ctrl + C</code> is merely a decision of the program. Yes, I think it totally depends on how the program would like to handle it. See the example I write below.
<h3>test.c</h3>
<pre class="lang-c prettyprint-override"><code>#include &lt;signal.h&gt;
#include &lt;stdio.h&gt;
#include &lt;unistd.h&gt;

static void ctrlC_Handler(int sig){
 if(sig == SIGINT){
 printf(&quot;(:KeyboardInterrupt:)\n&quot;);
 printf(&quot;&gt;&gt;&gt;&quot;);
 signal(SIGINT, ctrlC_Handler);
 }
}

static void welcome(){
 printf(&quot;Python 2.7.15rc1 (default, Nov 12 2018, 14:31:15)\n&quot;);
 printf(&quot;[GCC 7.3.0] on linux2\n&quot;);
 printf(&quot;Type \&quot;help\&quot;, \&quot;copyright\&quot;, \&quot;credits\&quot; or \&quot;license\&quot; for more information.\n&quot;);
 printf(&quot;&gt;&gt;&gt;&quot;);
 fflush(stdout);
}

int main(){
 welcome();
 signal(SIGINT, ctrlC_Handler);

 for(;;){
 pause();
 }

 return 0;
}
</code></pre>
compile it with <code>gcc test.c</code> and execute it <code>./a.out</code>. Try pressing <code>Ctrl + C</code>, you can see at least it mimics the behaviour(output) of the python program when you input <code>Ctrl + C</code>.
So, in my opinion, it's nothing special, but a human/programmer/author's decision on how to handle it.

I had this issue with Windows 10 Pro Build 18363 and Python 3.8.1. I was running some python scripts and was unable to stop some with <code>CTRL + C</code>, but <code>CTRL + BREAK</code> worked every time. <a href="https://docs.microsoft.com/en-us/windows/console/ctrl-c-and-ctrl-break-signals" rel="noreferrer" title="CTRL+C and CTRL+BREAK Signals">The Windows Docs</a> had this to say:

<blockquote>
 The CTRL+C and CTRL+BREAK key combinations receive special handling by console processes. By default, when a console window has the keyboard focus, CTRL+C or CTRL+BREAK is treated as a signal (SIGINT or SIGBREAK) and not as keyboard input... 
 
 CTRL+BREAK is always treated as a signal, but an application can change the default CTRL+C behavior in two ways that prevent the handler functions from being called:
 
 <ol>
 <li>The SetConsoleMode function can disable the ENABLE_PROCESSED_INPUT input mode for a console's input buffer, so CTRL+C is reported as keyboard input rather than as a signal.</li>
 <li>When SetConsoleCtrlHandler is called with NULL and TRUE values for its parameters, the calling process ignores CTRL+C signals. Normal CTRL+C processing is restored by calling SetConsoleCtrlHandler with NULL and FALSE values. This attribute of ignoring or not ignoring CTRL+C signals is inherited by child processes, but it can be enabled or disabled by any process without affecting existing processes. </li>
 </ol>
</blockquote>

Thus, <code>CTRL + C</code> seems to be a SIGINT and its actions can be modified by the program you are running. It seems that Python on Windows has been coded in such a way that <code>CTRL + C</code> is being processed as keyboard input rather than the SIGINT we are expecting. Fortunately for me I have the <code>CTRL + BREAK</code> keys on my keyboard and this works every time. 

For those of you who dont have <code>BREAK</code> on your keyboard, you can use the Windows On Screen virtual Keyboard. 

<ol>
<li>Press <code>win key + r</code> to open the run application program.</li>
<li>Type <code>osk</code>and press ok</li>
<li>On the virtual keyboard, press <code>ctrl + ScrLk</code> and this should kill the program.</li>
</ol>

Python fails to quit when using Ctrl-C in Powershell/Command Prompt, and instead gives out a "KeyboardInterrupt" string. 

Recently I've reinstalled Windows 10. Before the reinstall Ctrl-C quit python (3.5/2.7) fine, with no output. 

Does anyone know why this has started happening? Whether it's just a simple setting?

The only difference I can think of is I'm now on python 3.6. Ctrl-D works in Bash on Ubuntu on Windows, and Ctrl-C works fine in an activated anaconda python2 environment for quitting python.

 在Powershell/命令提示符中使用Ctrl-C时，Python无法退出，而是给出了一个"KeyboardInterrupt“字符串。 最近我重新安装了Windows10。在重新安装之前，按Ctrl-C可以退出python (3.5/2.7)，没有输出。 有人知道为什么会发生这种情况吗？是否只是一个简单的设置？ ...
