Python 文档字符串注释，大于和小于符号未显示

Question

I'm commenting Python code using docstrings. Note, this is just an example,

def credit_bonus(self, num_purchases: int, total_spend: float)->int:
    '''
    Calculates eligible and additional credit bonus for a customer, compared to previous
    yearly spends, and number of previous purchases.

    Additional credit ranking of 2, if current number of purchases > previous purchaces, 
    and current spend >= 95% previous spend.

    Return: customer's credit ranking
    '''

    ....

    return credit_rank

When the comment is displayed for this function, in VSCode, when hovering over this function in another module it is called from, the greater than symbol is not displayed. I have tried various escape characters, > , so far nothing works.

Is it possible to dispay, < and >, in Python docstrings?

Also, I know this is not a show stopper, nor imperative, just a minor convenience, will end up typing, greater than, instead.

Thanks and regards, njc

Working for function / method DocStrings, not for Class. Since posting, I'm still typing < and > in DocStrings, and I have noticed where it (now?) works, and where it doesn't. First some specs;

• Windows 10 Pro x64 20H2
• Visual Studio Code x64 1.52.1
• Microsoft Python extension for Visual Studio Code 2020.12.424452561

I does work for functions or methods,

def __new_connection(self)->sqlite3.Connection:
    '''
     __new_connection(self)`->`sqlite3.Connection:\n
     create a new connection using a connection string, time out, and isolation level settings.\n

     return:
         sqlite3.Connection.
    '''
    return sqlite3.connect(database=self.__con_str, timeout=self.__timeout, isolation_level=None, uri=True)

Typing the, acute or back quote, around the > , or in this case -> , will display < and > symbols, when the DocString is displayed for the method's description.

But

For class docstrings, it doesn't work.

class Broker:
    '''
     class wrapper for sqlite3 database objects and operations.\n
     transaction type: auto-commit.\n
     database type: file system database. not in-memory (:memory:)
     isolation level is set to None, i.e. auto-commit, cache is private.

     methods:\n
         __new_connection(self)->sqlite3.Connection
         creates a new sqlite3 connection object

         __cursor_execute(self, conn: sqlite3.Connection, sqlCmd: str, params: tuple=())->sqlite3.Cursor
        creates a cursor object, execute a parameterised sql statement
    '''

Doesn't work, no matter what symbol, or mark up, are placed around the < or >.

I shall post again if I find a work around for class DocStrings, assuming it doesn't work (still), if I do.
