Loc Scholarship - I've been exploring how to optimize my code and ran across pandas.at method. As far as i understood, pd.loc[] is used as a location based indexer where the format is:. Why do we use loc for pandas dataframes? When you use.loc however you access all your conditions in one step and pandas is no longer confused. There seems to be a difference between df.loc [] and df [] when you create dataframe with multiple columns.

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:

Can someone explain how these two methods of slicing are different? You can read more about this along with some examples of when not. I want to have 2 conditions in the loc function but the && When you use.loc however you access all your conditions in one step and pandas is no longer confused.

The Loc Method Gives Direct Access To The Dataframe Allowing For Assignment To Specific Locations Of The Dataframe.

You can refer to this question: This is in contrast to the ix method or bracket notation that. Or and operators dont seem to work.: I saw this code in someone's ipython notebook, and i'm very confused as to how this code works.

Loc Uses Row And Column Names, While Iloc Uses Their.

It seems the following code with or without using loc both compiles and runs at a similar speed: %timeit df_user1 = df.loc[df.user_id=='5561'] 100. Is there a nice way to generate multiple. Also, while where is only for conditional filtering, loc is the standard way of selecting in pandas, along with iloc.
