Do I have to pass 85 variables to function?

[Milfredo]

When I try and pass xx which is a dataframe I believe, I get the following message.

def load_horse_data(xx):

	horse_array[horse_count][0] = xx[hcount][race_number]
	horse_array[horse_count][1] = xx[hcount][todays_purse]

error message:

$ python pyfuncs.py
