Using a while loop : Similar to a for loop, we can also use while loop to iterate a list in reverse. Python’s inbuilt range() function is handy when you need to act a specific number of times. Output: [15, 14, 13, 12, 11, 10] Method 2: Using the reverse() built-in function. Example. Above array in reversed order: ALGORITHM: STEP 1: Declare and initialize an array. 1. Next, this C program to reverse array will reverse the given array elements using While Loop This method directly modifies the original list. C Program to Reverse an Array using While Loop. PROGRAM: Explanation : The commented numbers in the above program denote the step number below : We are using the same list as the above example. Using the reverse() method we can reverse the contents of the list object in-place i.e., we don’t need to create a new list instead we just copy the existing elements to the original list in reverse order. This reverse array program allows the user to enter the array size and the array elements. Python For loops can also be used for a set of various other things (specifying the collection of elements we want to loop over) Breakpoint is used in For Loop to break or terminate the program at any particular point; Continue statement will continue to print out the statement, and … STEP 3: Print the element arr[i] in each iteration. Example: from array import* my_array = array('i',[10,11,12,13]) my_array.reverse() print(my_array) The base condition of function is that if the length of the string is equal to 0, the string is returned.. If not equal to 0, the reverse function is recursively called to slice the part of the string except the first character and concatenate the first character to the end of the sliced string. Similar to lists, the reverse() method can also be used to directly reverse an array in Python of the Array module. Print each item in the cars array: for x in cars: print(x) Now, let us see how we can reverse an array in Python created with the Array module. Reverse operation in python can be defined as a process of turning the order of the input assigned to a variable from back to front or front to back. Looping Array Elements. Reverse an Array or List in Python. Here in this program, we will learn how to reverse an array using Python concept. The range() function enables us to make a series of numbers within the given range. How to write a C Program to Reverse an Array using While Loop, For loop, Functions, and Recursion with example?. Example of reverse string in python using recursion.. Depending on how many arguments you pass to the range() function, you can choose where that sequence of numbers will begin and end as well as how big the difference will be between one number and the next. Reverse an array means the last element should be displayed first, followed by second last element and so on.In Python there are 3 ways to reverse an array such: 1) Reversing a list in-place with the list.reverse() method In python, to reverse an array we will use the reverse() method and it will reverse all the element present in array. Reverse an array in Python. Remove List Duplicates Reverse a String Add Two Numbers ... Python Loop Through an Array Python Glossary. You can use the for in loop to loop through all the elements of an array. First, we have calculated the length of the list using … Few stylistic points about your current solution: use print() as a function for Python 3 compatibility; on the other hand, because you are running it on Python 2.x, you may avoid creating an extra list with range() and use xrange() function (differences); according to PEP8, you need to have spaces around the operators ; you can use end -= 1 shortcut instead of end = end - 1 STEP 2: Loop through the array in reverse order that is, the loop will start from (length of the array - 1) and end at 0 by decreasing the value of i by 1. 3. Recursion function. This operation can be achieved by any kind of logic involving the conditional statements of python, such as for loop, while conditional statement, if condition, etc. Using reverse() Method. Let us discuss how to reverse an array in Python? It reverses an array at its original location, hence doesn’t require extra space for storing the results. In a previous tutorial, we covered the basics of Python for loops, looking at how to iterate through lists and lists of lists.But there’s a lot more to for loops than looping through lists, and in real-world data science work, you may want to use for loops with other data structures, including numpy arrays and pandas DataFrames.
