Python で手動で遅延させる方法

import time
time.sleep(5)   # Delays for 5 seconds. You can also use a float value.

import timewhile True:
    print("This prints once a minute.")
    time.sleep(60) # Delay for 1 minute (60 seconds).

from time import sleep
sleep(0.1) # Time in seconds.

>>> from time import sleep
>>> sleep(4)

>>> def party_time():
...     print('hooray!')
... 
>>> sleep(3); party_time()
hooray!
