2D List in Python Error

Question

The input format:
2 2
2 3
4 5

1st line represents the dimension. 2 is the row. 2 is the column.
The next lines represent the elements in the list

However, my codes below are wrong

n, p = [int(x) for x in input().split()]
#n= row, p= col

num=[]
col=[]

for i in range(n):
num1, num2=[ float(x) for x in input().split()]

col.append(num1)
col.append(num2)
num.append(col)

print(num)

How to make a 2D list in Python properly so that the output is:
[ [2,3],
[4,5] ]

Answer 1

for i in range(n):
col=[]
num1, num2=[ float(x) for x in input().split()]

col.append(num2)

Answer 3

Hello Khairul,
What if 1st number is greater than 1, is it possible?

2 2
2 3
4 5

If it was possible, how the resuting `list` will be?
