255 – Unicode codepoints

Use the built-in function ord convert one-character strings into their Unicode codepoints:

print(ord("a"))  # 97
print(ord("A"))  # 65

Use the built-in function chr to convert a Unicode codepoint into the corresponding character:

print(chr(97))  # "a"
print(chr(65))  # "A"

These conversions work for all valid Unicode codepoints, including emojis.
