sleep()是在python 3的time()模塊中定義的。有時，需要破壞程序的流程，以便可以進行其他幾次執行，或者僅僅是由於所需的實用程序。在這種情況下，sleep()可以派上用場，它提供了一種準確而靈活的方式來在任何時間段內停止代碼流。此函數討論此函數的見解。
語法：sleep(sec)參數：sec：要求停止代碼的秒數。返回：VOID。
代碼1：展示sleep()
Python3
# Python code to demonstrate
# working of sleep()
import time
# printing the start time
print("The time of code execution begin is:", end ="")
print(time.ctime())
# using sleep() to hault the code execution
time.sleep(6)
# printing the end time
print("The time of code execution end is:", end ="")
print(time.ctime())輸出：
The time of code execution begin is:Mon Apr 9 20:57:10 2018 The time of code execution end is:Mon Apr 9 20:57:16 2018
應用：
sleep()用於許多應用程序。如果以固定間隔重複執行後台線程，則可以借助sleep()來實現。另一個流行的應用程序是使用sleep()逐字母打印單詞，以獲得良好的用戶接口。後者由下麵的代碼表示。
代碼2：演示sleep()的應用
Python3
# Python code to demonstrate
# application of sleep()
import time
# initializing string
strn = "GeeksforGeeks"
# printing geeksforgeeks after delay
# of each character
for i in range(0, len(strn)):
print(strn[i], end ="")
time.sleep(2)輸出：
GeeksForGeeks
Note: Visible effect of sleep() can be seen in the local editor.
代碼3：在列表中創建時間延遲
Python3
# importing time package
import time
# creating a time delay of 5 seconds
time.sleep(5)
# creating and Initilizing a list
myList = ['Jai', 'Shree', 'RAM', 5, 'August', 2020]
# the list will be displayed after the delay of 5 seconds
print(myList)輸出：
延遲5秒後，我們將獲得以下輸出：
['Jai', 'Shree', 'RAM', 5, 'August', 2020]
代碼4：在元組中創建時間延遲
Python3
# importing time package
import time
# creating a time delay of 4 seconds
time.sleep(4)
# creating and Initilizing a tuple
mytuple = ('Anil Kumbl', 'Sachin Tendulkar', 'Sunil Gavaskar', 'Rahul Dravid', 'Mahendra Singh Dhoni',
'Dennis Lillee', 'Muttiah Muralitharan', 'Shane Warne')
# the tuple will be displayed after the delay of 4 seconds
print(mytuple)輸出：
延遲4秒後，我們將獲得以下輸出：
('Anil Kumbl', 'Sachin Tendulkar', 'Sunil Gavaskar', 'Rahul Dravid',
'Mahendra Singh Dhoni', 'Dennis Lillee', 'Muttiah Muralitharan', 'Shane Warne')
代碼5：創建多個時間延遲
Python3
# importing time package
import time
# creating and Initilizing a list
Languages = ['Java', 'C++', 'Python', 'Javascript', 'C#', 'C', 'Kotlin']
# creating a time delay of 5 seconds
time.sleep(5)
# the list will be displayed after the delay of 5 seconds
print(Languages)
for lan in Languages:
# creating a time delay of 13 seconds
time.sleep(13)
# After every 13 seconds an item of list will be displayed
print(lan)輸出：
延遲5秒後，列表將顯示為：
['Java', 'C++', 'Python', 'Javascript', 'C#', 'C', 'Kotlin']
然後，每隔13秒，列表項將顯示為：
Java C++ Python Javascript C# C Kotlin
代碼6：列表理解中的時間延遲
Python3
# importing time package
import time
# creating and Initilizing a list
cricketers = ['Anil Kumble', 'Sachin Tendulkar', 'Sunil Gavaskar', 'Rahul Dravid', 'Mahendra Singh Dhoni',
'Dennis Lillee', 'Muttiah Muralitharan', 'Shane Warne']
# time delay of 7 seconds is created
# after every 7 seconds item of list gets displayed
cricketers = [(time.sleep(7), print(cric)) for cric in cricketers]輸出：
每隔7秒，列表中的項目將顯示為：
Anil Kumble Sachin Tendulkar Sunil Gavaskar Rahul Dravid Mahendra Singh Dhoni Dennis Lillee Muttiah Muralitharan Shane Warne
代碼7：在列表中創建3分鍾的延遲
Python3
# importing time package
import time
# creating and Initilizing a list
Languages = ['Java', 'C++', 'Python', 'Javascript', 'C#', 'C', 'Kotlin']
# creating a time delay of 3 minutes
time.sleep(3 * 60)
# the list will be displayed after the delay of 3 minutes
print(Languages)輸出：
延遲3分鍾後，列表將顯示為：
['Java', 'C++', 'Python', 'Javascript', 'C#', 'C', 'Kotlin']
