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 isnโt 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.

Mean, Var, and Std in Python โ HackerRank Solution
Problem:
meanThe mean tool computes the arithmetic mean along the specified axis.
import numpy my_array = numpy.array([ [1, 2], [3, 4] ]) print numpy.mean(my_array, axis = 0) #Output : [ 2. 3.] print numpy.mean(my_array, axis = 1) #Output : [ 1.5 3.5] print numpy.mean(my_array, axis = None) #Output : 2.5 print numpy.mean(my_array) #Output : 2.5
By default, the axis is None. Therefore, it computes the mean of the flattened array.
varThe var tool computes the arithmetic variance along the specified axis.
import numpy my_array = numpy.array([ [1, 2], [3, 4] ]) print numpy.var(my_array, axis = 0) #Output : [ 1. 1.] print numpy.var(my_array, axis = 1) #Output : [ 0.25 0.25] print numpy.var(my_array, axis = None) #Output : 1.25 print numpy.var(my_array) #Output : 1.25
By default, the axis is None. Therefore, it computes the variance of the flattened array. stdThe std tool computes the arithmetic standard deviation along the specified axis.
import numpy my_array = numpy.array([ [1, 2], [3, 4] ]) print numpy.std(my_array, axis = 0) #Output : [ 1. 1.] print numpy.std(my_array, axis = 1) #Output : [ 0.5 0.5] print numpy.std(my_array, axis = None) #Output : 1.11803398875 print numpy.std(my_array) #Output : 1.11803398875
ย By default, the axis is None. Therefore, it computes the standard deviation of the flattened array.ย
Output Format :
First, print the mean.
Second, print the var.
Third, print the std.
Sample Input :
2 2 1 2 3 4
Sample Output :
[ 1.5 3.5] [ 1. 1.] 1.11803398875
Task :
You are given a 2-D array of size NXM.
Your task is to find:The mean along axis 1The var along axis 0The std along axis
Input Format :
The first line contains the space separated values of N and M.
The next N lines contains M space separated integers.
