Python 序列包括字串、列表、元組等。我們可以使用不同的方式合併 Python 序列的元素。讓我們來看看一些以相反順序迭代列表的範例。
在這個例子中，我們有一個作為序列的列表，並使用while循環以相反的順序進行迭代 -
# Creating a List
mylist = ["Jacob", "Harry", "Mark", "Anthony"]
# Displaying the List
print("List = ",mylist)
# Length - 1
i = len(mylist) - 1
# Iterate in reverse order
print("Display the List in Reverse order = ")
while i >= 0 :
print(mylist[i])
i -= 1
List = ['Jacob', 'Harry', 'Mark', 'Anthony'] Display the List in Reverse order = Anthony Mark Harry Jacob
在這個例子中，我們有一個作為序列的列表，並使用for迴圈以相反的順序進行迭代-
# Creating a List
mylist = ["Jacob", "Harry", "Mark", "Anthony"]
# Displaying the List
print("List = ",mylist)
# Iterate in reverse order
print("Display the List in Reverse order = ")
for i in range(len(mylist) - 1, -1, -1):
print(mylist[i])
List = ['Jacob', 'Harry', 'Mark', 'Anthony'] Display the List in Reverse order = Anthony Mark Harry Jacob
在這個範例中，我們有一個List作為一個序列，並使用reversed()方法以相反的順序進行迭代 -
# Creating a List
mylist = ["Jacob", "Harry", "Mark", "Anthony"]
# Displaying the List
print("List = ",mylist)
# Iterate in reverse order using reversed()
print("Display the List in Reverse order = ")
[print (i) for i in reversed(mylist)]
List = ['Jacob', 'Harry', 'Mark', 'Anthony'] Display the List in Reverse order = Anthony Mark Harry Jacob
在此範例中，我們將 List 作為序列，並使用負索引以相反順序迭代它 −
## Creating a List
mylist = ["Jacob", "Harry", "Mark", "Anthony"]
# Displaying the List
print("List = ",mylist)
# Iterate in reverse order using negative indexing
print("Display the List in Reverse order = ")
[print (i) for i in mylist[::-1]]
List = ['Jacob', 'Harry', 'Mark', 'Anthony'] Display the List in Reverse order = Anthony Mark Harry Jacob
