parameteres transfer in python

Question

I am new to Python and a bit confused about parameters transfer: I have 2 methods:

def convert(self, ipnb, indices = []):
    with self.fopen(ipnb, u'r') as f:
        emptyIndicesList = not indices
        #some code

def test_read(self):
    s = self.convert(self, u'test.ipynb')
    #some code

I encounter 2 issues:

If I run the code as is self.fopen(ipnb, u'r') as f throws... But if I change with self.fopen(ipnb, u'r') as f to self.fopen(u'test.ipynb', u'r') as f it works properly
emptyIndicesList is false, I expect it to be true, since I think that I am using default parameter - empty list What am I missing in parameter transfer? How the above issues should be solved?

Thanks :)

You are passing the context as a first argument to the function convert.

Change s = self.convert(self, u'test.ipynb') to s = self.convert(u'test.ipynb') which shall resolve both of your issues.
