Using Python I need to convert an int to a six digit hex that I can use as a background colour in CSS. Any ideas how to do that?

The int is a primary key of a model in Django.

Convert an int to a 6-digit hex:

In [10]: '{0:06X}'.format(16746513)
Out[10]: 'FF8811'

Check that the hex is equivalent to the int:

In [9]: int('FF8811',16)
Out[9]: 16746513

IF you really just have an integer then "#" + hex(value) will return the appropriate code to use. However, if you have a tuple of three 0-225 integers then you need to convert the three of them to hex values, pad them if necessary and join them together. You can do this with a single string formatting operation.

hex = "#%02x%02x%02x" % (r, g, b)

The %02x means zero pad the number to two digits which the x means convert to lowercase hexidecimal. Use X if you want uppercase.
