Array Sorting: How to sort an array of integers in Python3?
By Priyam SurARRAY SORTING in Python
Array sorting can be of two types:
- Ascending Order Sorting: The arrangement of elements of the array is from smallest to largest number.
- Descending Order Sorting: The arrangement of elements of the array is from largest to smallest number.
There are a lot of algorithms through which we can do the sorting. The image below is an example of insertion sort.

The sorting in python is easy, as there’s a built-in function sort(), which directly sorts the elements of a list(array).
The code snippet is given below:
PROGRAM:
print("Input Array Elements:")
l=list(map(int,input().split(" ")))
l.sort()
a=[0 for i in range(len(l))]
print("Input your choice:")
print("1.Arrange the Array in Ascending Order")
print("2.Arrange the Array in Descending Order")
c=int(input("Choice(1/2):"))
if(c==1):
for i in range(len(l)):
print(l[i],end=" ")
elif(c==2):
for i in range(len(l)):
a[len(l)-1-i]=l[i]
for i in range(len(a)):
print(a[i],end=" ")
else:
print("Choose either 1 or 2.")OUTPUT 1:
Input Array Elements: 4 5 6 2 1 5 7 9 8 2 6 8 9 Input your choice: 1.Arrange the Array in Ascending Order 2.Arrange the Array in Descending Order Choice(1/2):2 9 9 8 8 7 6 6 5 5 4 2 2 1
OUTPUT 2:
Input Array Elements: 45 65 87 21 54 69 40 32 78 98 75 Input your choice: 1.Arrange the Array in Ascending Order 2.Arrange the Array in Descending Order Choice(1/2):1 21 32 40 45 54 65 69 75 78 87 98
