Python: Sort a list, iterable

Built-in function 'sorted' takes an iterable as argument and return a new sorted list from the items in iterable.

 

Signature

sorted(iterable, *, key=None, reverse=False)

 

Example1: To sort the list in ascending order.

ascending_order_list = sorted(my_list)

 

Example 2: To sort the list in descending order.

descending_order_list = sorted(my_list, reverse=True)

 

Find the below working application.

 

sort_list.py

my_list = [2, 1, 3, 8,  4, 9, 5]

ascending_order_list = sorted(my_list)
descending_order_list = sorted(my_list, reverse=True)

print('my_list : ', my_list)
print('ascending_order_list : ', ascending_order_list)
print('descending_order_list : ', descending_order_list)

 

Output

my_list :  [2, 1, 3, 8, 4, 9, 5]
ascending_order_list :  [1, 2, 3, 4, 5, 8, 9]
descending_order_list :  [9, 8, 5, 4, 3, 2, 1]
