Loc Scholarship

Loc Scholarship - I've been exploring how to optimize my code and ran across pandas.at method. 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. Why do we use loc for pandas dataframes? As far as i understood, pd.loc[] is used as a location based indexer where the format is:. 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. You can refer to this question: Business_id ratings review_text xyz 2 'very bad' xyz 1 ' Or and operators dont seem to work.: Is there a nice way to generate multiple.

Is there a nice way to generate multiple. This is in contrast to the ix method or bracket notation that.

When you use.loc however you access all your conditions in one step and pandas is no longer confused. This is in contrast to the ix method or bracket notation that. The loc method gives direct access to the dataframe allowing for assignment to specific locations of the dataframe. You can read more about this along with some examples of when not.
