Thanks for contributing an answer to Stack Overflow! would raise a KeyError). Note the square brackets here instead of the parenthesis (). So, the answer to your question is: In prior versions, using .loc[list-of-labels] would work as long as at least one of the keys was found (otherwise it would raise a KeyError). KeyError in the future, you can use .reindex() as an alternative. df1 = pd.DataFrame (data_frame, columns= ['Column A', 'Column B', 'Column C', 'Column D']) df1. without creating a copy: The signature for DataFrame.where() differs from numpy.where().

Pandas is an open source Python package that is most widely used for data science/data analysis and machine learning tasks. Use this with care if you are not dealing with the blocks. ), and then find the max in that object (or row). NA values are treated as False. Alternatively, if it matters to index them numerically and not by their name (say your code should automatically do this without knowing the names of the first two columns) then you can do this instead: Additionally, you should familiarize yourself with the idea of a view into a Pandas object vs. a copy of that object. Python is a great language for doing data analysis, primarily because of the fantastic ecosystem of data-centric python packages. Find centralized, trusted content and collaborate around the technologies you use most. pandas get cell values. two methods that will help: duplicated and drop_duplicates. If you continue to use this site we will assume that you are happy with it. Also, if the index has duplicate labels and either the start or the stop label is duplicated, df = pd. If the indexer is a boolean Series, access the corresponding element or column.
