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.

Problem:

zeros
The zeros tool returns a new array with a given shape and type filled with 0’s.

import numpy

print numpy.zeros((1,2))                    #Default type is float
#Output : [[ 0.  0.]] 

print numpy.zeros((1,2), dtype = numpy.int) #Type changes to int
#Output : [[0 0]]

ones
The ones tool returns a new array with a given shape and type filled with 1’s.

import numpy

print numpy.ones((1,2))                    #Default type is float
#Output : [[ 1.  1.]] 

print numpy.ones((1,2), dtype = numpy.int) #Type changes to int
#Output : [[1 1]]   

Task :

You are given the shape of the array in the form of space-separated integers, each integer representing the size of different dimensions, your task is to print an array of the given shape and integer type using the tools numpy.zeros and numpy.ones. 

---

Input Format :

A single line containing the space-separated integers. 

Constraints :

• 1 <= each inteager <= 3

Output Format :

First, print the array using the numpy.zeros tool and then print the array with the numpy.ones tool. 

---

Sample Input :

3 3 3

Sample Output :

[[[0 0 0]
  [0 0 0]
  [0 0 0]]

 [[0 0 0]
  [0 0 0]
  [0 0 0]]

 [[0 0 0]
  [0 0 0]
  [0 0 0]]]
[[[1 1 1]
  [1 1 1]
  [1 1 1]]

 [[1 1 1]
  [1 1 1]
  [1 1 1]]

 [[1 1 1]
  [1 1 1]
  [1 1 1]]]

Explanation :

Print the array built using numpy.zeros and numpy.ones tools and you get the result as shown.
