**Introduction To Python**

**Python **is a widely-used, interpreted, **object-oriented, and high-level programming** language with dynamic semantics, used for general-purpose programming. It was created by **Guido van Rossum**, and first released on **February 20, 1991**.

**Python **is a computer programming language often used to build websites and software, automate tasks, and conduct data analysis. It is also used to create various machine learning algorithm, and helps in Artificial Intelligence. Python is a general purpose language, meaning it can be used to create a variety of different programs and isn’t specialized for any specific problems. This versatility, along with its beginner-friendliness, has made it one of the most-used programming languages today. A survey conducted by industry analyst firm **RedMonk **found that it was the most popular programming language among developers in **2020**.

Reduce Function in Python – HackerRank Solution

**Problem:**

Given a list of rational numbers,find their product.

**Concept**

The `reduce()`

function applies a function of two arguments cumulatively on a list of objects in succession from left to right to reduce it to one value. Say you have a list, say `[1,2,3]`

and you have to find its sum.

>>> reduce(lambda x, y : x + y,[1,2,3]) 6

You can also define an initial value. If it is specified, the function will assume initial value as the value given, and then reduce. It is equivalent to adding the initial value at the beginning of the list. For example:

>>> reduce(lambda x, y : x + y, [1,2,3], -3) 3 >>> from fractions import gcd >>> reduce(gcd, [2,4,8], 3) 1

**Input Format**

First line contains , the number of rational numbers.

The of next lines contain two integers each, the numerator( ) and denominator( ) of the rational number in the list.

**Constraints**

**Output Format**

Print only one line containing the numerator and denominator of the product of the numbers in the list in its simplest form, i.e. numerator and denominator have no common divisor other than .

**Sample Input 0**

3 1 2 3 4 10 6

**Sample Output 0**

5 8

**Explanation 0**

Required product is 1/2 3/4 10/6 = 5/8
