Return PLS-00306 During login in with python
Oracle procedure PM_USER_LOGIN_SP has one or more parameters, each of them having its own data type. When calling that procedure, you must match number and data type of each of them.
For example, if it expects 3 parameters, you can't pass only 2 (nor 4) of them (because of wrong number of arguments (parameters)).
If parameter #1 is DATE, you can't pass letter A to it (because of a wrong type). Note that  DATEs are kind of "special", because something that looks like a date to us, humans (such as 20.01.2018, which is today) passed to Oracle procedure's DATE data type parameter must really be a date. '20.01.2018' is a string, so either pass date literal, such as DATE '2018-01-20' or use appropriate function with a format mask, TO_DATE('20.01.2018', 'dd.mm.yyyy').
Therefore, have a look at the procedure first, pay attention to what it expects. Then check what you pass to it.
