python如何手动实现阻塞

Question

python 如何手动实现阻塞？

令py脚本一直阻塞直到强制退出（KeyboardInterrupt）

之前用

while True:
    pass

发现cpu占用太高了。。。

Answer 1

1. Use time.sleep

while True:
    ＃ 等待一年
    time.sleep(60*60*24*365)
    
# 直接等待一百年
time.sleep(60*60*24*365*100)

2.Use threading.Condition

condition=threading.Condition()
condition.acquire()
condition.wait()

2. Use wait for keyboard response

Python implements pressing any key to continue

Answer 2

while True:
    time.sleep(1)
