get return value from store procedure pymssql

Question

i'm setting up my connection and return error value from sql-server with pymssql framework in python

this is my Python code with pymssql framework

with pymssql.connect(self.server,self.userID,self.password,self.database) as conn:
    with conn.cursor() as cursor:
        msg = curosr.callproc("TESTVALUE")
        print (msg["return"])

and i got error from msg, there is no return variable

this is what i can do if im on C# language to get return value:

errCode = (int)Cmd.Parameters["return"].Value;

this is my store procedure

ALTER PROCEDURE dbo.TESTVALUE
AS
BEGIN
    #Some query
    IF 1 == 1 #Some Logic
       Return -631 #The Return Value that i need to get
END

i need to get the Return -631 value with python code with pymssql framework

how i can get that return value ini python? please help.

You can use an anonymous code block to execute the stored procedure and retrieve the return value:

sql = """\
SET NOCOUNT ON;
DECLARE @rv int;
EXEC @rv = dbo.TESTVALUE;
SELECT @rv;
"""
crsr.execute(sql)
return_value = crsr.fetchone()[0]
print(return_value)  # -631
