blocks|key|301936|text|对我来说(或者Python2.x中的raw_input()+)似乎没问题。或者，如果您想要暂停特定的秒数，可以使用time.sleep()。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|301937|import+time
print("something")
time.sleep(5.5)++++#+Pause+5.5+seconds

It Seems fine to me (or <code>raw_input()</code> in Python 2.X). Alternatively, you could use <code>time.sleep()</code> if you want to pause for a certain number of seconds.
<pre><code>import time
print(&quot;something&quot;)
time.sleep(5.5) # Pause 5.5 seconds
print(&quot;something&quot;)
</code></pre>

blocks|key|518850|text|我假设您想暂停而不输入。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|518851|使用：|518852|time.sleep(seconds)|offset|length|518853|entityMap|0|LINK|mutability|MUTABLE|url|http://docs.python.org/library/time.html#time.sleep^0|0|0|0|J|0|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|Q|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|R|8|@]|9|@$F|S|G|T|1|U]]|A|$]]|$1|H|3|-4|5|6|7|V|8|@]|9|@]|A|$]]]|I|$J|$5|K|L|M|A|$N|O]]]]

I assume you want to pause without input.
Use:

blocks|key|518874|text|我也遇到过类似的问题，我使用的是signal：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|518875|import+signal

def+signal_handler(signal_number,+frame):
++++print+"Proceed+..."

signal.signal(signal.SIGINT,+signal_handler)
signal.pause()|code-block|syntax|javascript|518876|因此，您为信号SIGINT注册了一个处理程序，并暂停等待任何信号。现在，在你的程序之外(例如，在bash中)，你可以运行kill+-2+<python_pid>，它会向你的python程序发送信号2(即SIGINT)。您的程序将调用已注册的处理程序并继续运行。|offset|length|style|CODE|518877|entityMap^0|0|0|1O|K|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@$I|R|J|S|K|L]]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

I have had a similar question and I was using signal:

<pre><code>import signal

def signal_handler(signal_number, frame):
 print "Proceed ..."

signal.signal(signal.SIGINT, signal_handler)
signal.pause()
</code></pre>

So you register a handler for the signal SIGINT and pause waiting for any signal. Now from outside your program (e.g. in bash), you can run <code>kill -2 &lt;python_pid&gt;</code>, which will send signal 2 (i.e. SIGINT) to your python program. Your program will call your registered handler and proceed running.

blocks|key|302048|text|非常简单：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|302049|raw_input("Press+Enter+to+continue+...")

Very simple:
<pre><code>raw_input(&quot;Press Enter to continue ...&quot;)
print(&quot;Doing something...&quot;)
</code></pre>

blocks|key|518946|text|在Linux中，您可以在后台发出kill+-TSTP+<pid>命令并停止进程。因此，它就在那里，但不会消耗CPU时间。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|518947|然后，使用kill+-CONT+<pid>，它就会关闭并再次运行。|518948|entityMap^0|G|G|0|5|G|0^^$0|@$1|2|3|4|5|6|7|J|8|@$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|M|8|@$9|N|A|O|B|C]]|D|@]|E|$]]|$1|H|3|-4|5|6|7|P|8|@]|D|@]|E|$]]]|I|$]]

In Linux, you can issue <code>kill -TSTP &lt;pid&gt;</code> to the background and stop a process. So, it's there, but not consuming CPU time.
Then later, <code>kill -CONT &lt;pid&gt;</code> and it's off and running again.

blocks|key|302148|text|为了与Python2/3兼容，您可以通过six库使用input：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|302149|import+six
six.moves.input(+'Press+the+<ENTER>+key+to+continue...'+)|code-block|syntax|javascript|302150|entityMap^0|K|3|Q|5|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@$9|N|A|O|B|C]|$9|P|A|Q|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|R|8|@]|D|@]|E|$I|J]]|$1|K|3|-4|5|6|7|S|8|@]|D|@]|E|$]]]|L|$]]

For cross Python 2/3 compatibility, you can use <code>input</code> via the <code>six</code> library:

<pre><code>import six
six.moves.input( 'Press the &lt;ENTER&gt; key to continue...' )
</code></pre>

blocks|key|519043|text|通过这种方法，您只需按下指定的任意键即可恢复程序：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|519044|import+keyboard

By this method, you can resume your program just by pressing any specified key you've specified that:
<pre><code>import keyboard
while True:
 key = keyboard.read_key()
 if key == 'space': # You can put any key you like instead of 'space'
 break
</code></pre>
The same method, but in another way:
<pre><code>import keyboard
while True:
 if keyboard.is_pressed('space'): # The same. you can put any key you like instead of 'space'
 break
</code></pre>
Note: you can install the <a href="https://github.com/boppreh/keyboard" rel="nofollow noreferrer"><code>keyboard</code></a> module simply by writing this in you shell or cmd:
<pre><code>pip install keyboard
</code></pre>

I've been using the <code>input</code> function as a way to pause my scripts:
<pre><code>print(&quot;something&quot;)
wait = input(&quot;Press Enter to continue.&quot;)
print(&quot;something&quot;)
</code></pre>
Is there a formal way to do this?

Correct way to pause a Python program

Linux

我一直使用input函数作为暂停脚本的一种方式：print("something")wait = input("Press Enter to continue.")print("something")有没有一种正式的方法来做这件事？
