How to treat a hex as string?

I have some hex number such as 0x61cc1000 and I want to input them to a function which only takes string. I want to treat the hex numbers as strings without any change.

If I use str() function it converts it to int and then treats it as string. But I want to keep the original hex value.

Your problem is that you're using str:

>>> str(0x61cc1000)
'1640763392'  # int value of the hex number as a string

That's because first 0x61cc1000 is evaluated as an int, then str performed on the resulted int.

You want to do:

"{0:x}".format(0x61cc1000)

Or

'{:#x}'.format(0x61cc1000)

As already stated in other answer, you can simply:

>>> hex(0x61cc1000)
'0x61cc1000'

See 6.1.3.1. Format Specification Mini-Language for details.

If you want to have 0x at the beginning you may use #x format like this:

'{:#x}'.format(74954)

If you want the hex string representation of any integer, just pass it through the hex built-in.

>>> n = 0x61cc1000
>>> n
1640763392
>>> hex(n)
'0x61cc1000'
