There is a small mistake : note
for i in range (0, m):
Mat.append([])

in respect of no. of rows we have to adjust '0'(Zeroes) to number of columns not rows.

[adarshgoswami]

Here's a smaller version of it:
r=int(input("Enter the number of rows"))
c=int(input("Enter the number of columns"))
mat=[ ]

for i in range(r):
mat.append([ ])
for j in range(c):
x=int(input("Enter the element"))
mat[i].append(x)

print(mat)

plz make video on stock market ohcl chart how will make ohcl chart if api is avalbel then

[dineshnalli]

mat = [[int(input()) for x in range (C)] for y in range(R)]

1. Write a python code to initialize two 3x3 Matrices (A & B) using 2D list using nested loop and range() function and perform addition of Matrices. Make sure to store the result in 3rd 3x3 Matric (C).

at 05:18 in line:4, m changes into n

[krishnanarwani]

here's the answer in less no. of steps

m=int(input('enter rows:'))
n=int(input('enter columns:'))

mat=[[ int(input()) for x in range(n) ] for y in range(m)]

print(mat)

[ffernando]

how I have to do for a matrix 5x2 or 4x3?

[dabbopabblo]

Or in 1 line just do,
mat.append([[0] * n]*m)

[sal]

Here's the easiest way to do this:

m=int(input('enter rows:'))
n=int(input('enter columns:'))

mat=[ int(input()) for x in range(n) ] for y in range(m)]

for j in mat:
print(j)

Thank you. I was looking for this everywhere.!!!

Simple Solution
lst1=[[0, 0, 0], [0, 0, 0]]
for i in range(0, 2):
lst1[i][0] = int(input("Enter Number"))
lst1[i][1] = int(input("Enter Number"))
print(lst1)

[kayceekelvin]

how do i do this but instead of taking an input from user, i use random numbers to fill the 2d list

His voice is like Rakesh Mahanthi. To know who he is type worst interview ever.
