Question

I put an elif statement in a while statement, and I expected that when it finishes what's inside it, it'd repeat the while command. What actually happens is the console spams "unknown command" indefinitely. How do I fix this?

while O == 0:
    if bla bla bla
        O = 1
    elif O != 1: #This should happen after it takes all if commands above me into account
        print('unknown command')

Answer 1

显然，您的if bla bla bla测试不匹配。

但是，由于O == 0为真，O != 1也是如此，您永远不会更改O的值，从而产生无限循环。无限循环在每次迭代时打印'unknown command'，填满你的控制台。

Answer 2

只要你的O == 0为真，elif语句也是True（o！= 1），除非if语句为True且O更改为1。所以当执行elif语句时，它会转到infiniteloop，因为在elif中o的值没有改变。或者在elif

中打印后添加break

elif command keeps repeating inside while command
