Pandas is a Python data analysis package based on NumPy for data analysis. It provides a large number of advanced data structures and data processing methods. Pandas has two main data structures:SeriesAndDataFrame.

Convert a Python array to a Series object: index and values attributes, for example:3. DataFrame
DataFrame is a table-type data structure. It provides ordered columns and different types of column values. For example, converting a dictionary composed of NumPy arrays into a DataFrame object: the next article is: Using Python for data analysis (8) pandas-summary statistics and computing, if you are interested, please follow this blog and add comments for discussion.
