## Python Math: Exercise-37 with Solution

Write a Python program to find the sum of the following decimal numbers and display the numbers in sorted order.

Sample Solution :-

Python Code :

``````from decimal import *
data = list(map(Decimal, '2.45 2.69 2.45 3.45 2.00 0.04 7.25'.split()))
print("Sum: ", sum(data))
print("Sorted order: ", sorted(data))
```
```

Sample Output:

```Sum:  20.33
Sorted order:  [Decimal('0.04'), Decimal('2.00'), Decimal('2.45'), Decimal('2.45'), Decimal('2.69'), Decimal('
3.45'), Decimal('7.25')]
```

## Python: Tips of the Day

Getting the last element of a list:

some_list[-1] is the shortest and most Pythonic.

In fact, you can do much more with this syntax. The some_list[-n] syntax gets the nth-to-last element. So some_list[-1] gets the last element, some_list[-2] gets the second to last, etc, all the way down to some_list[-len(some_list)], which gives you the first element.

You can also set list elements in this way. For instance:

```>>> some_list = [1, 2, 3]
>>> some_list[-1] = 5 # Set the last element
>>> some_list[-2] = 3 # Set the second to last element
>>> some_list
[1, 3, 5]
```

Note that getting a list item by index will raise an IndexError if the expected item doesn't exist. This means that some_list[-1] will raise an exception if some_list is empty, because an empty list can't have a last element.
