Displaying an integer as text in pygame

In pygame I am trying to print the text '10 x 10'. The 10 is stored as an integer in sizeOfGrid variable. My current code is:

text = font.render((str(sizeOfGrid),'x',str(sizeOfGrid)), 1, (10, 10, 10))
textpos = (32,210)
screenDisplay.blit

When I run the program it returns the error exceptions.TypeError: text must be string or unicode. I don't understand this error or what is wrong as I have converted the 10 into a string.

The first argument of font.render must be of the datatype string or unicode. You probably just need to change that. Instead of (str(sizeOfGrid),'x',str(sizeOfGrid) you may write something like "%d x %d" % tuple([sizeOfGrid]*2).

The "%d x %d" part is the string format, where we ask for two digit arguments. With an tuple sample (4, 4) this would give us the string "4 x 4".

To add arguments to the string, we use modulo followed by the arguments, that is % tuple([sizeOfGrid]*2) where [sizeofGrid]*2 is [10, 10] and tuple([sizeOfGrid]*2) is (10, 10), which happen to be our two digit arguments. You can use it like this:

text = font.render("%d x %d" % tuple([sizeOfGrid]*2), 1, (10, 10, 10))

I would use something like this

screenDisplay.blit(font.render("{0}x{0}".format(sizeOfGrid), True, (10, 10, 10)), (32, 210))

font.render expects first arguement a string, you are providing a tuple.

note:I used {0}x{0} since both values are sizeOfGrid.
