SAS to Python: MLE with only one variable

I'm currently trying to write SAS Codes in Python, but I got a problem. Right now I'm trying to do a MLE, but SAS only uses one variable.

This is the following SAS Code:

SET krm.mortgage;
IF 700 < FICO_Orig_time < 750;
RUN;
ods graphics on;
PROC MEANS DATA = krm.mortgage_FICO750;
VAR default_time;
RUN;
PROC LOGISTIC DATA = krm.mortgage_FICO750 DESCENDING; 
MODEL default_time = / RSQUARE LINK = Probit;
RUN;
QUIT;
ods graphics off;

The thing that's bugging me is that if I want to get a MLE in Python, it requires two arguments

Probit(endog, exog).fit()

My dependent variable endog is of course "default_time", but what should be my exog, as the original code in SAS doesn't depend on anything else?

May you provide sample data in a [reproducible form](https://stackoverflow.com/questions/20109391)? – Bill Huang Oct 23 '20 at 14:42
It's a way to get whatever the equivalent of an 'odds ratio' is in probit regression. – Reeza Oct 23 '20 at 15:29
