Python Program to Reverse List

by

In this article, we will show you, How to write a Python Program to reverse List Items with practical example. Before you start, please refer List article to understand everything about Lists.

Python Program to Reverse List Items

This python program allows user to enter the length of a List. Next, we used For Loop to add numbers to the list.

TIP: Python reverse function is used to reverse the elements in a List

# Python Program to Reverse List Elements

NumList = []

Number = int(input("Please enter the Total Number of List Elements: "))
for i in range(1, Number + 1):
    value = int(input("Please enter the Value of %d Element : " %i))
    NumList.append(value)

NumList.reverse()
print("\nThe Result of a Reverse List =  ", NumList)

Python Program to Reverse List Items without using reverse

In this program, we are using While loop. Inside the while loop we performed the Swapping with the help of third variable. I suggest you to refer Swap two Numbers article to understand the logic

# Python Program to Reverse List Elements

NumList = []

Number = int(input("Please enter the Total Number of List Elements: "))
for i in range(1, Number + 1):
    value = int(input("Please enter the Value of %d Element : " %i))
    NumList.append(value)

j = Number - 1
i = 0

while(i < j):
    temp = NumList[i]
    NumList[i] = NumList[j]
    NumList[j] = temp
    i = i + 1
    j = j - 1
    
print("\nThe Result of a Reverse List =  ", NumList)

Python Program to Reverse List Items using Functions

This program is same as above. However, we separated the logic using Functions

# Python Program to Reverse List Elements

def reverse_list(NumList, num):
    j = Number - 1
    i = 0
    while(i < j):
        temp = NumList[i]
        NumList[i] = NumList[j]
        NumList[j] = temp
        i = i + 1
        j = j - 1
    
NumList = []
Number = int(input("Please enter the Total Number of List Elements: "))
for i in range(1, Number + 1):
    value = int(input("Please enter the Value of %d Element : " %i))
    NumList.append(value)
    
reverse_list(NumList, Number)
print("\nThe Result of a Reverse List =  ", NumList)

Python Program to Reverse Items in a List using Recursion

This program will reverse List items by calling functions recursively

# Python Program to Reverse List Elements

def reverse_list(NumList, i, j):
    if(i < j):
        temp = NumList[i]
        NumList[i] = NumList[j]
        NumList[j] = temp
        reverse_list(NumList, i + 1, j-1)
    
NumList = []
Number = int(input("Please enter the Total Number of List Elements: "))
for i in range(1, Number + 1):
    value = int(input("Please enter the Value of %d Element : " %i))
    NumList.append(value)
    
reverse_list(NumList, 0, Number - 1)
print("\nThe Result of a Reverse List =  ", NumList)
