there are (at least) two ways accomplishing this.  in your
situation, you can either use the string format operator
(%) like this...

output = open('%s.$%d$' % (file_name, block_number), 'wb')
(%s indicates a string and %d indicates an integer)

... or you can directly convert the number (or any object)
to a string using the str() built-in function, like this:

output = open(file_name + '.$' + str(block_number) + '$', 'wb')

hope this helps!!
