Python RGB to Hex number (not a string!)

I need to convert R, G, B colour values into 0xrrggbb format. Yes, there are a lot of solutions out there, but they all return "0xrrggbb" (a string) rather than 0xrrggbb (a hex number).

What are the options to achieve this, please?

Edit: to clarify what I'm trying to achieve: I'm reading RGB values from a GIF (using PIL), converting them to hex and storing in a list.

Neopixels require data in the following format: ledNumber[i] = 0xdeadbeef The hex value cannot be a string, so I need a way to convert the RGB values to hex whilst keeping it as a number.

I hope this clarifies.
