import numpy as np
matrix = np.array([[1,2,3],[4,5,6],[7,8,9],[10,11,12]] )
print(matrix.T)

without using numpy

Edit: for Both Python2 and Python3

Python3

[*zip(*matrix)]

Python2

zip(*matrix)

Use zip:

mymatrix=[(1,2,3),(4,5,6),(7,8,9),(10,11,12)] 
myTransposedMatrix = list(zip(*mymatrix))

>>> myTransposedMatrix
[(1, 4, 7, 10), (2, 5, 8, 11), (3, 6, 9, 12)]

You need to install numpy in order to import it Numpy transpose returns similar result when
applied on 1D matrix 

import numpy  
mymatrix=[[1,2,3],[4,5,6]] 
print(mymatrix) 
print("\n") 
print(numpy.transpose(mymatrix))
