Finding no of columns and rows based on a variable - Python

Coding
1

Hello,

I am trying to figure out a formula which would give me number of (equal sized) rows and columns to be drawn on a grid based on a variable.

Python :

row,column = makeGrid(variable)

eg :

if variable = 1 i.e. only one element is to be place in complete grid so number of column and row will be 1.

if variable = 2 then we need either 2 row,1 column or 2column,1 row so that two elements can be place in two

if variable =3 : 2 rows,2columns

if variable=4 : 2 rows,2columns

Thanks !

What if the number is bigger than 4? Does it add columns or rows? Or is 4 the cutoff?

def get_grid( num ):
    divisor = int( math.sqrt( num ) )
    v = divisor
    h = divisor
    if h * v < num:
        h += 1
    if h * v < num:
        v += 1
    return h, v

Hello Crapper,
It should go beyond the limit of 4 ,Above images are just for example.-Thanks

Hello Theodox,
Awesome ! It works. - Thanks
Just curious to explore more, where to explore for grid math (or what keywords on google) ?

Close, and as much as I’d like to be able to claim my ancestors invented the toilet, unfortunately I cannot.
