In this simple python program, we need to sort an array in python. It's a sorting python program.
To understand this example, you should have knowledge of the following Python programming topics:
In this simple python program for beginners, we need to sort the elements in an array in ascending order. The array is a set of elements of the same datatype. To sort the array, use nested for loops. The outer loop is used to take an element from the array, and the inner loop is to compare that with every other element in the array. When an element with a lower value is found, it will be swapped with the comparing element using an if condition in python. Repeat the loops to sort every element in the array to get all the elements sorted.
Let us take an example array with elements [5, 3, 1, 2 4], then we take the first element 5 and compare that with the other elements, so we compare it with 3, and it is smaller than 5, so it gets swapped with 3. Finally, we get the array sorted. In this Basic python program on arrays, we are using a predefined array with some elements. Then we use a temp variable initialize with zero. After displaying the original array we use nested
for loop and swap the elements using temp variable, finally print the sorted array using a
STEP 1: Initialize the array with some predefined values.
STEP 2: Define a variable temp with the value zero.
STEP 3: We print the original array using a for loop using a range method in python programming.
STEP 4: Start the outer
for loop from zero to length of array for comparing one element in the array.
STEP 5: Open the inner
for loop from i+1 to the array's length to compare the element with all other elements in the array.
STEP 6: Use an if condition to check if the selected element is greater than the comparing element,
STEP 7: Swap the selected element with the lesser element and do that till the end of for loop to get the array fully sorted in python.
STEP 8: Print the sorted array using for loop and print in the python programming language
arr = [5, 2, 3, 4, 1]; temp = 0; print("Elements in original array: "); # printing the original array for i in range(0, len(arr)): print(arr[i]), for i in range(0, len(arr)): for j in range(i+1, len(arr)): # comparing the elements using nested for loop if(arr[i] > arr[j]): temp = arr[i]; arr[i] = arr[j]; # swapping the elements arr[j] = temp; print(); print("Array sorted in ascending order: "); for i in range(0, len(arr)): print(arr[i]),
Elements in original array 5, 2, 3, 4, 1 Array sorted in ascending order 1, 2, 3, 4, 5
