AttributeError: tuple object has no attribute 'realari' when I tried to print the tap position

Hello;

I did a program which increases a TAPs position in an OLTC transformer. However, when I want to see the tap position I have an Error. Someone knows how could I obtain the TAP position with print command? or maybe I need to use another, What do you think?

Set the TAP position

TAP=1.000+Tap_pos
ierr, TRF = psspy.two_winding_data_6(ibus_trafo, jbus_trafo, '1', realari4=TAP)

For obtaining the value I used the next command:

print("TAP = " TRF.realari[3])
print("TAP = " TRF.realari4)

I obtained the next error message depending on the print used:

AttributeError: 'tuple' object has no attribute 'realari'
attributeError: tuple object has no attribute 'realari4'

The API is returning ierr, realaro. Print ierr and realaro to see the content. The value returned in realaro is the actual transforrmer resistance and reactande, i.e. a tuple. Note that the API is not returning the ratio of the transformer or the tap position.

you can use print(TRF) to see the structure of TRF. Probably try print(TRF[0].realari[3]).

Thank you but it does not work. Now it says that this property is a float, so I tried to convert to string but it does not work. AttributeError: 'float' object has no attribute 'realari'
