With the help of sympy.Matrix().col() method, we can extract the columns of the matrix.

Syntax : sympy.Matrix().col()
Return : Return the col of a matrix.

Example #1 :
In the given example we can see that the sympy.Matrix.col() method is used to extract the columns of a matrix.

# Import all the methods from sympy
from sympy import *

# use the col() method for matrix
gfg_val = Matrix([[1, 2], [2, 1]]).col(1)

print(gfg_val)

Output :

Matrix([[2], [1]])

Example #2 :

from sympy import *

# use the col() method for matrix
gfg_val = Matrix([[1, 2], [2, 3], [23, 45]]).col(0)

print(gfg_val)

Output :

Matrix([[1], [2], [23]])
