Typo in pandas tutorial 1? #287

Open davidmcnamee opened 4 years ago

davidmcnamee commented 4 years ago

Hey, I was just going through the pandas tutorial and wasn't sure whether this is a typo or if I'm misunderstanding.

https://github.com/Kaggle/learntools/blob/886f5c215de079287f21e2d3a92bd852fb95d105/notebooks/pandas/raw/tut_1.ipynb#L279

it's a lot more convenient to index df.loc['Apples':'Potatoes'] than it is to index something like df.loc['Apples', 'Potatoet] (t coming after s in the alphabet)

Should the second code snippet be df.iloc['Apples':'Potatoes']? It was just explained that df.iloc[0:10] gives you indices 0,...,9 but df.loc[0:10] gives you indices 0,...,10; and then I wasn't sure how they got df.loc['Apples', 'Potatoet].

@uWaterloo I will say second code snippet can't be df.iloc['Apples':'Potatoes']. Because iloc uses only integer type indexed value. If you want to use string value as index for accessing data from pandas dataframe then you have to use Pandas Dataframe loc method.

Now the second issue about df.loc['Apples', 'Potatoet']: I will say typo mistake is about not mentioning apostrophe mark after Potatoet
Basically it will include Potatoet if there is any in the given dataframe. Moreover they have mentioned to use df.loc['Apples', 'Potatoes'] over df.loc['Apples', 'Potatoet'].
