    Transpose of a matrix

    from numpy import *

    arr=array(

    [

    (1,2,3),(4,5,6)

    ]

    )

    newmat=[[0 for x in range(len(arr))]for y in range(len(arr[0]))]

    for i in range(len(newmat[0])):

    for j in range(len(newmat)):

    newmat[j][i]=arr[i][j]

    #Displaying Transpose

    for i in range(len(newmat)):

    for j in range(len(newmat[0])):

    print(newmat[i][j],end=" ")

    print("n")

    hie, I do enjoy programing in python. I come from Mechanical background, still Python seems easy. I don't understand how to study C and CPP. they are tough….

    from numpy import *

    arr1=array([

    [1,2,3],

    [4,5,6]])

    arr2=arr1.reshape(3,2)

    arr3=ones((2,2))

    for i in range(2):

    for j in range(2):

    c=0

    for k in range(3):

    f=arr1[i][k]*arr2[k][j]

    c=c+f

    arr3[i][j]=c

    print(arr3)

    num2=int(input('Enter second number'))

    res=0

    for i in range(0,num1):
