2D List in Python Error

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] ]

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?
