How to escape Unicode in Python 3

Question

So I know that the character "Latin Small Letter Sharp S" ß is at Unicode Point U+00DF and I know how to escape this in Python 3 as a string: \u00DF.

However, I know that there are other unicode prefixes for the larger codepoints (such as U+260E: Black Telephone)

I have seen the uppercase U being used such as \U00DF and i have also seen \x being used.

My question is when do i use those. For instance many emoji are just given as U+260x. And my thought is to use a capital U and fill in 12 0s before those digits but when do I use an \x and when do I know to use leading zeros (and how many)

All of this is me guessing because I can't find any documentation.

Answer 1

The \x takes two hex digits. The lower-case \u takes four hex digits. The upper-case \U takes eight hex digits.
