Does pyodbc support any form of named parameters?

I know sqlite3 has

data = {'test_col': 012345679}
sqlite3_conn.execute("""
    UPDATE test_db SET test_col = :test_col
    ;""", data)

and mysql-connector-python has

data = {'test_col': 012345679}
mysql_conn.execute("""
    UPDATE test_db SET test_col = %(test_col)s
    ;""", data)

but does pyodbc support any form of named parameters? I like being able to just pass a dict to the execute method. It is very convenient, and with some of my queries, such as INSERT INTO ... ON DUPLICATE KEY UPDATE, it is needed.

It doesn't support named parameters, but bound parameters passed in the correct order are fairly straightforward:

x = "This"
y = 345

mssql_cur.execute("SELECT * FROM mytable WHERE colx = ? AND coly = ?", x, y)

or

mssql_cur.execute("SELECT * FROM mytable WHERE colx = ? AND coly = ?", (x, y))

More details and options here, such as passing executemany parameters:

Good luck!
