Type unicode character using python variable

The code point of '🐍' in hex is '0001f40d', and I store this code point in variable hex_snake. Then I want to call this icon using '\Uhex_snake' but got an error. Any ideas on expanding variables inside of quotes?

The \U escape code can only be used in string literals, and must be followed by eight hexadecimal digits between 00000000-0010FFFF. But you can just store the character in your variable instead and print with f-strings:

>>> snake = '\U0001f40d'  # or '\N{SNAKE}' or chr(0x1f40d)
>>> print(f'snake = {snake}')
snake = 🐍

If you have hex digits in a string and don't want to change, the following works, but is more complicated:

>>> snake = '0001f40d'
>>> print(f'snake = {chr(int(snake,16))}')
snake = 🐍

The given string can be turned into an int, which can then be used as an argument for chr.

>>> x = '0001f40d'
>>> chr(int(x, base=16))
'🐍'
