Concatenate numpy arr in HackerRank

 import numpy


n,m,p = map(int,input().split())

arr1 = numpy.array([input().split() for i in range(n)],int)
arr2 = numpy.array([input().split() for i in range (m)],int)

arr3 = numpy.concatenate((arr1,arr2),axis=0)

print(arr3)

first array size 4*2
second array size 3*2

Sample input :

4 3 2 1 2 1 2 1 2 1 2 3 4 3 4 3 4

Sample output :
[[1 2]
 [1 2]
 [1 2]
 [1 2]
 [3 4]
 [3 4]
 [3 4]]

Mean, Var, and Std in numpy HackerRank

  mean The  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. var The  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. std The  std ...

Min and Max in numpy HackerRank

min The tool  min  returns the minimum value along a given axis. import numpy my_array = numpy.array([[2, 5], [3, 7], [1, 3], [4, 0]]) print numpy.min(my_array, axis = 0) #Output : [1 0] print numpy.min(my_array, axis = 1) #Output : [2 3 1 0] print numpy.min(my_array, axis = None) #Output : 0 print numpy.min(my_array) #Output : 0 By default, the axis value is  None . Therefore, it finds the minimum over all the dimensions of the input array. max The tool  max  returns the maximum value along a given axis. import numpy my_array = numpy.array([[2, 5], [3, 7], [1, 3], [4, 0]]) print numpy.max(my_array, axis = 0) #Output : [4 7] print numpy.max(my_array, axis = 1) #Output : [5 7 3 4] print numpy.max(my_array, axis = None) #Output : 7 print numpy.max(my_array) ...
