My teacher gave this snippet for Accepting input from user and creating a matrix using list.

Question

I am not able to understand the row and column part here. can a sample matrix be generated so that I can understand how the matrix will look?

r,c=3,2
x=[]
for i in range(r):
x.append([0]*c)
for i1 in range(r):
for i2 in range(c):
x[i1][i2]=int(input())
print()

Answer 1

[[x00, x01], ← columns = 2
[x10, x11],
[x20, x21]]
↑rows = 3

Answer 2

You can use print(x) to see what values are saved in the matrix.
