How do I convert a hex string to an int in Python?

I may have it as "0xffff" or just "ffff".

I want to create a function that will accept any old string (will usually be a single word) and from that somehow generate a hexadecimal value between #000000 and #FFFFFF, so I can use it as a colour for a HTML element.

Maybe even a shorthand hex value (e.g: #FFF) if that's less complicated. In fact, a colour from a 'web-safe' palette would be ideal.

I have this string: Hello world !! and I want to print it using Python as 48:65:6c:6c:6f:20:77:6f:72:6c:64:20:21:21.

hex() works only for integers.

How can it be done?

I've got this string containing multiple hexadecimal numbers:

let input = '\x01\x01\x02\x01';

I would like to see this transformed into: 1121 (the decimal representation of each hex number)

How would I go about this? I've tried numerous things, but the only output I get are some diamond shapes with a questionmark inside of it or syntax errors. Many thanks in advance!

What is the best way to convert a string to hex and vice versa in C++?

Example:

• A string like "Hello World" to hex format: 48656C6C6F20576F726C64
• And from hex 48656C6C6F20576F726C64 to string: "Hello World"
