Arrays in Python | HackerRank Solution

Hello coders, today we are going to solve Arrays HackerRank Solution in Python.

Arrays in Python


The NumPy (Numeric Python) package helps us manipulate large arrays and matrices of numeric data.

To use the NumPy module, we need to import it using:

import numpy


NumPy array is a grid of values. They are similar to lists, except that every element of an array must be the same type.

import numpy

a = numpy.array([1,2,3,4,5])
print a[1]          #2

b = numpy.array([1,2,3,4,5],float)
print b[1]          #2.0

In the above example, numpy.array() is used to convert a list into a NumPy array. The second argument (float) can be used to set the type of array elements.


You are given a space separated list of numbers.
Your task is to print a reversed NumPy array with the element type float.

Input Format

A single line of input containing space separated numbers.

Output Format

Print the reverse NumPy array with type float.

Sample Input

1 2 3 4 -8 -10

Sample Output

[-10.  -8.   4.   3.   2.   1.]

Solution – Arrays in Python

import numpy

def arrays(arr):
    return(numpy.array(arr[::-1], float))
arr = input().strip().split(' ')
result = arrays(arr)
