Equivalent function of datenum(datestring) of Matlab in Python

Question

In Matlab, when I run "datenum" function as the following;

datenum(1970, 1, 1);

I get the following output:

719529

I'm trying to find the equivalent function or script which is gonna give me the same output. But, unfortunately I couldn't find an enough explanation on the internet to do this.

I have looked at this tutorial: https://docs.python.org/2/library/datetime.html, but it didn't help.

Could you tell me, how can I get the same output in python?

Thanks,

The previous answers return an integer. MATLAB's datenum does not necessarily return an integer. The following code retuns the same answer as MATLAB's datenum:

from datetime import datetime as dt

def datenum(d):
    return 366 + d.toordinal() + (d - dt.fromordinal(d.toordinal())).total_seconds()/(24*60*60)

d = dt.strptime('2019-2-1 12:24','%Y-%m-%d %H:%M')
dn = datenum(d)
