python终止循环_Python：如果while条件在循环期间发生变化，如何在运行时结束while循环？...

I need some help with code in a text based game I am trying to make. My game uses health, and the code starts off with "while health>0:", and in another point in the game, when health eventually =0, the loop still continues. How do I make the loop end when health=0, without finishing the whole loop.

Here is an example:

health=100

while health>0:

print("You got attacked")

health=0

print("test")

Should the code not be stopping when health=0, and not print "test"? How to I get it to stop when health=0? The code I wrote deducts health based on the users actions, so the times when health=0 can vary. I want to end the code whenever health=0 Any help would be appreciated.

解决方案

The condition is only evaluated at the start of each iteration. It does not get checked in the middle of an iteration (e.g. as soon as you set to health to zero).

To explicitly exit the loop, use break:

while health>0:

...

if some_condition:

break

...
