Array sorting in ascending and descending order using python.

 

We need sorted() function to sort the given list in ascending or descending order.

The syntax is as follows: sorted(list, key=..., reverse=....)

>> Lets see first list sorting:- 

#First we need to specify an array and save it in a variable.

a = [2.2, 2.3233, 2322, 32.23, 2, 32.2, 5.11, 4, 0.1, 0.1]

#Secondly we'll be using a sorted() function to sort out the given array.

print('sorting in ascending order:', sorted(a))

#Lastly we'll be using reverse=True for the array to be in descending order.

print('sorting in descending order:', sorted(a, reverse = True))

#Output:

sorting in ascending order: [0.1, 0.1, 2, 2.2, 2.3233, 4, 5.11, 32.2, 32.23, 2322]

sorting in descending order: [2322, 32.23, 32.2, 5.11, 4, 2.3233, 2.2, 2, 0.1, 0.1]

>> Then lets see set{} sorting:-

a = {2.2, 2.3233, 2322, 32.23, 2, 32.2, 5.11, 4, 0.1, 0.1}

#Output:[0.1, 0.1, 2, 2.2, 2.3233, 4, 5.11, 32.2, 32.23, 2322]

>> Tuple() sorting:-

a = (2.2, 2.3233, 2322, 32.23, 2, 32.2, 5.11, 4, 0.1, 0.1)

#Output:[0.1, 0.1, 2, 2.2, 2.3233, 4, 5.11, 32.2, 32.23, 2322]

>> Dictionary{:1, :2} sorting:-

a = {2.2:1, 2.3233:2, 2322:3, 32.23:4, 2:5, 32.2:6, 5.11:7, 4:8, 0.1:9, 0.1:10}

#Output:[0.1, 0.1, 2, 2.2, 2.3233, 4, 5.11, 32.2, 32.23, 2322]

>> Then sorting a string:-

b = 'python is a programming language!'

print(sorted(b))

#Output: [' ', ' ', ' ', ' ', '!', 'a', 'a', 'a', 'a', 'e', 'g', 'g', 'g', 'g', 'h', 'i', 'i', 'l', 'm', 'm', 'n', 'n', 'n', 'o', 'o', 'p', 'p', 'r', 'r', 's', 't', 'u', 'y']

Note: If we sort a string then it will be sorted in alphabetical order, first privilege is given to blank space and special characters.
