Being new to python and running it in the Jupyter notebooks, sometimes you get errors that just don’t make sense and it’s a bit frustrating when you can’t make sense of the error. Let’s take this gem:

/home/aron/anaconda3/lib/python3.9/site-packages/IPython/core/interactiveshell.py:3397: FutureWarning: In a future version of pandas all arguments of read_csv except for the argument 'filepath_or_buffer' will be keyword-only.
  exec(code_obj, self.user_global_ns, self.user_ns)

So what the hell does that mean? I understand pandas, arguments, and what read_csv is but what is keyword-only???

It turns out that this keyword only means that instead of relying on the order of the argument, you simply need to use the keyword for anything except for filepath or buffer…

So this piece of code throws the error:

# Load in the general demographics data.
azdias = pd.read_csv('Udacity_AZDIAS_Subset.csv', ';')

And this is the error fixed:

# Load in the general demographics data.
azdias = pd.read_csv('Udacity_AZDIAS_Subset.csv', delimiter=';')
