Program Plan Intro
List slicing:
- • The process of choosing a range of data items from a list is called as list slicing.
- • In Python, an expression that chooses a sub list from a sequence is called as a slice.
- • A slice is a span of data items that are taken out from a list.
- • Generally, the slice expression has start and end indices as its inputs.
- • If the end index is not given, then the list’s length is taken as the end index.
- • The start and end indices in the list slice expression can also have the negative integers as their values.
- • The negative integers indicate the location that is relative to the end of the list.
Syntax:
In python, the list slice expression with a negative index has the below format.
#Create an expression to slice the list
listname[negative_index:]
or
#Create an expression to slice the list
listname[:negative_index]

- Sum of two squares def sum_of_two_squares(n): Some positive integers can be expressed as a sum of two squares of some positive integers greater than zero. For example, 74 = 49 + 25 = 72 + 52. This function should find and return a tuple of two positive integers whose squares together add up to n, or return None if the parameter n cannot be broken into a sum of two squares. To facilitate the automated testing, the returned tuple must present the larger of its two numbers first. Furthermore, if some integer can be broken down to a sum of squares in several ways, return the breakdown that maximizes the larger number. For example, the number 85 allows two such representations 72 + 62 and 92 + 22 , of which this function must return (9, 2). The technique of two approaching indices that start from the beginning and end of a sequence, respectively, and approach each other until they meet somewhere, used in the function two_summers in one of our class examples, is directly applicable to this…arrow_forwardSum of two squares def sum_of_two_squares(n): Some positive integers can be expressed as a sum of two squares of some positive integers greater than zero.
