if i have got to create a nxn sized table of integers using randint how can i do that, i know i can create a list and append randint, but how to make so it’s not in single line but rather n elements in each lines and n such lines!
please explain this with code + how you want the output to look
You could use nested for loops:
for i in range(n): for i in range(n):
n are the sizes you wish to have
Is this exercise related?
so i was working on this problem :
no its not exercise related
am i not suppose to ask such questions
do we have a place in codecademy where i can discuss such general problem , since i have completed python now::::: sory for being lengthy
Okabe needs to renovate the Future Gadget Laboratory after he tried doing some crazy experiments! The lab is represented as an n by n square grid of integers. A good lab is defined as a lab in which every number not equal to 1 can be expressed as the sum of a number in the same row and a number in the same column. In other words, for every x, y such that 1 ≤ x, y ≤ n and ax, y ≠ 1, there should exist two indices s and t so that ax, y = ax, s + at, y, where ai, j denotes the integer in i-th row and j-th column.
Help Okabe determine whether a given lab is good!
The first line of input contains the integer n (1 ≤ n ≤ 50) — the size of the lab.
The next n lines contain n space-separated integers denoting a row of the grid. The j-th integer in the i-th row is ai, j (1 ≤ ai, j ≤ 105).
Print “Yes” if the given lab is good and “No” otherwise.
You can output each letter in upper or lower case.
1 1 2
2 3 1
6 4 1
we have the corner bar, ideal for this kind of question, i moved this topic to corner bar
What? This instructions are very vague. where on earth do
s and a whole bunch of other things come from?
y are the coordinates on the board? so 0,0 for top left corner? except they count top corner as 1,1?
How is the board generated? random numbers?
i mean, that is simple:
# python2 from random import randint x = int(raw_input("number: ")) board =  for a in range(x): row =  for b in range(x): row.append(randint(0,5) board.append(row) for c in board: print " ".join(c)
