The key isn't restricted to being an integer; it can be any nonmutable data type, including an integer, float, tuple, or string.

键并不限制为整数；它可以是任何不易变的数据类型，包括 integer、float、tuple 或 string。

youdao

Tuples can be used as keys if they contain only strings, numbers, or tuples; if a tuple contains any mutable object either directly or indirectly, it cannot be used as a key.

如果元组中只包含字符串和数字，它可以做为关键字，如果它直接或间接的包含了可变对象，就不能当做关键字。
