I have a simple python script file which contains following 3

import pandas
df = pandas.read_csv('testfile.csv')
print(df[0:3])
Can I incorporate above in a D program?
I see there is pyd package for using python in D:

It is a bizarre quirk, I think because interfaces do not
necessarily point to objects with RTTI (though this can be
statically determined, so I am not sure that is valid), but when
you do typeid on an interface, it gives
