I've seen the docs and i've seen previous similar questions (1, 2), but i still find myself unable to understand how they are. It seems the following code with or without using loc both compiles and runs at a similar speed: Why do we use loc for pandas dataframes? I saw this code in someone's ipython notebook, and i'm very confused as to how this code works. I've been exploring how to optimize my code and ran across pandas.at method. Also, while where is only for conditional filtering, loc is the standard way of selecting in pandas, along with iloc. As far as i understood, pd.loc[] is used as a location based indexer where the format is:. There seems to be a difference between df.loc [] and df [] when you create dataframe with multiple columns. Is there a nice way to generate multiple. You can read more about this along with some examples of when not.

%Timeit Df_User1 = Df.loc[Df.user_Id=='5561'] 100.

When you use.loc however you access all your conditions in one step and pandas is no longer confused. I've been exploring how to optimize my code and ran across pandas.at method. There seems to be a difference between df.loc [] and df [] when you create dataframe with multiple columns. The loc method gives direct access to the dataframe allowing for assignment to specific locations of the dataframe.
