How do you print ascending and descending order using for loop in Python?

ALGORITHM:

  1. STEP 1: Declare and initialize an array.
  2. STEP 2: Loop through the array and select an element.
  3. STEP 3: The inner loop will be used to compare the selected element from the outer loop with the rest of the elements of the array.
  4. STEP 4: If any element is less than the selected element then swap the values.

How do you reverse a list in Python without using reverse or slicing?

Another way to reverse python list without the use of any build-in methods is using loops. Create an empty list to copy the reversed elements. In the for loop, add the iterator as a list element at the beginning with the new list elements. So in that way, the list elements will be reversed.
