Initialize empty matrix in Python

Question

I am trying to convert a MATLAB code in Python. I don\'t know how to initialize empty matrix in Python.

MATLAB Code:

demod4(1) = [];

<

Answer 1

M=[]
n=int(input())
m=int(input())
for j in range(n):
   l=[]
   for k in range(m):
       l.append(0)
   M.append(l)
print(M)

This is the traditional way of doing it matrix[m,n], However, python offers many cool ways of doing so as mentioned in other answers.
