## 睡眠如何在Python中延迟时间
|
||
|
|
|
||
|
|
Python标准库中的`time`模块包含函数`sleep()` ，该函数将程序暂停给定的秒数。
|
||
|
|
|
||
|
|
例：
|
||
|
|
```
|
||
|
|
import time
|
||
|
|
|
||
|
|
for letter in 'hello, world!':
|
||
|
|
print(letter)
|
||
|
|
time.sleep(2) # sleep 2 seconds between each print
|
||
|
|
```
|
||
|
|
|
||
|
|
浮点数可以作为`sleep()`的参数给出，以获得更精确的睡眠时间。
