print(("{0:05X}".format(int("1C", 16))))

0001C

print(("{0:05X}".format(0x1C)))

You can also make use of Python's format command for string formatting. This allows you to specify a fill character, in this case 0 and a width as follows:

print "{:0>2s}".format('9')

This would display:

09

You have a string, just zero-fill it to the desired width using str.zfill():

hexNumber.zfill(2)

The %x formatter is for integers only.

Demo:

>>> hexNumber = '9'
>>> hexNumber.zfill(2)
'09'
