reverse()是Python編程語言中的一種內置方法,可就地反轉列表對象。
用法:
list_name.reverse()
參數:
There are no parameters
返回值:
The reverse() method does not return any value but reverse the given object from the list.
代碼#1:
# Python3 program to demonstrate the  
# use of reverse method  
   
# a list of numbers 
list1 = [1, 2, 3, 4, 1, 2, 6]  
list1.reverse()  
print(list1)  
  
# a list of characters 
list2 = ['a', 'b', 'c', 'd', 'a', 'a']  
list2.reverse()  
print(list2) 輸出:
[6, 2, 1, 4, 3, 2, 1] ['a', 'a', 'd', 'c', 'b', 'a']
錯誤:
When anything other than list is used in place of list, then it returns an AttributeError
代碼#2:
# Python3 program to demonstrate the  
# error in reverse() method 
   
# error when string is used in place of list 
string = "abgedge" 
string.reverse()  
print(string)輸出:
Traceback (most recent call last):
  File "/home/b3cf360e62d8812babb5549c3a4d3d30.py", line 5, in 
    string.reverse() 
AttributeError:'str' object has no attribute 'reverse' 
實際應用:
給定一個數字列表,請檢查該列表是否為回文。
注意:palindrome-sequence向後讀取相同的內容
代碼#3:
# Python3 program for the  
# practical application of reverse()  
  
list1 = [1, 2, 3, 2, 1] 
  
# store a copy of list 
list2 = list1.copy()   
  
# reverse the list 
list2.reverse()  
  
# compare reversed and original list  
if list1 == list2:
    print("Palindrome")  
else:
    print("Not Palindrome") 輸出:
Palindrome
