I can't speak generally, but in cx_Oracle you either execute a query like this:
result = cursor.var(cx_Oracle.NUMBER)
cursor.execute(":1 := test_proc()", [result])
print(result.getvalue())
or you use the non-standard callfunc method:
print(cursor.callfunc("test_proc", cx_Oracle.NUMBER))
As a general solution, one might wrap a stored procedure that returns
a value into a stored procedure that has an output parameter and call
it with callproc. Some implementations might include a return value
in the parameter list anyway.
