Creating a Dataframe from Pandas series - In data science, data is represented in various formats, such as tables, graphs, or any other types of structures. One of the most common data structures used to represent data is a DataFrame, which can be create
The output is a pandas DataFrame with the cleaned data. A pandas DataFrame is a two-dimensional data structure similar to a table in a SQL database or in a spreadsheet. You can read more about DataFrames at bit.ly/2BlWl6K. Now that the data has been cleaned and loaded, it’s time ...
