How to Rotate Array Position in Console Terminal using Python

Submitted by razormist on Saturday, September 7, 2024 - 23:37.

In this tutorial, we will program 'How to Rotate Array Positions in a Console Terminal using Python.' We will learn how to rotate the array positions by shifting the numbers. The objective is to safely rotate the array positions in an incrementing order. I will provide a sample program to demonstrate the actual coding process in this tutorial.

This topic is very easy to understand. Just follow the instructions I provide, and you will be able to do it yourself with ease. The program I will show you covers the basics of programming for rotating array positions. I will do my best to provide you with a simple method for incrementing the order of array positions. So, let's start coding

Getting Started:

First you will have to download & install the Python IDLE's, here's the link for the Integrated Development And Learning Environment for Python https://www.python.org/downloads/.

Creating Main Function

This is the main function of the application. The following code will display a simple GUI in terminal console that will display program. To do this, simply copy and paste these blocks of code into the IDLE text editor.
  1. def reverse(start, end, arr):
  2.  
  3.        
  4.         no_of_reverse = end-start+1
  5.  
  6.  
  7.         count = 0
  8.         while((no_of_reverse)//2 != count):
  9.                 arr[start+count], arr[end-count] = arr[end-count], arr[start+count]
  10.                 count += 1
  11.         return arr
  12.  
  13.  
  14. def left_rotate_array(arr, size, d):
  15.  
  16.        
  17.         start = 0
  18.         end = size-1
  19.         arr = reverse(start, end, arr)
  20.  
  21.         start = 0
  22.         end = size-d-1
  23.         arr = reverse(start, end, arr)
  24.  
  25.         start = size-d
  26.         end = size-1
  27.         arr = reverse(start, end, arr)
  28.         return arr
  29.  
  30. ret = False
  31.  
  32.  
  33. while True:
  34.         print("\n================= Rotate Array Position =================\n\n")
  35.  
  36.  
  37.  
  38.         arr = [1, 2, 3, 4, 5, 6, 7, 8, 9]
  39.         size = 9
  40.         n = int(input("Enter a number 1-9: "))
  41.  
  42.  
  43.         print('Original array:', arr)
  44.  
  45.  
  46.         if(n <= size):
  47.                 print('Rotated array: ', left_rotate_array(arr, size, n))
  48.         else:
  49.                 n = n % size
  50.                 print('Rotated array: ', left_rotate_array(arr, size, n))
  51.  
  52.  
  53.         opt = input("\nDo you want to try again?(yes/no): ")
  54.  
  55.         if opt.lower() == 'yes':
  56.                 ret=False
  57.         elif opt.lower() == 'no':
  58.                 ret=True
  59.                 print("Exiting program....")
  60.  
  61.         else:
  62.                 print("Please enter yes/no:")
  63.                 break
  64.  
  65.         if ret == False:
  66.                 continue

This Python script rotates an array to the left by a specified number of positions using a reverse function. It repeatedly prompts the user for a number to rotate the array and displays the rotated result. The loop continues until the user decides to exit the program.

Output:

There you have it we successfully created How to Rotate Array Position in Console Terminal using Python. I hope that this simple tutorial help you to what you are looking for. For more updates and tutorials just kindly visit this site. Enjoy Coding!
