Create a series star_ratings with the number of stars corresponding to each review in the dataset. def stars(row): if row.country == 'Canda': return 3 elif row.points >= 95: return 3 elif row.points < 85: return 1 else: return 2 star_ratings = reviews.apply(stars, axis = 1)编...
Pandas is a special tool that allows us to perform complex manipulations of data effectively and efficiently. Inside pandas, we mostly deal with a dataset in the form of DataFrame. DataFrames are 2-dimensional data structures in pandas. DataFrames consist of rows, columns, and data.Calculating...
This helps in understanding the characteristics of the dataset without having to examine each data point individually. How can I calculate summary statistics for a DataFrame in Pandas? You can use the describe() method in Pandas DataFrame to generate summary statistics. It provides count, mean, ...

Morph an input dataset of 2D points into select shapes, while preserving the summary statistics to a given number of decimal points through simulated annealing. It is intended to be used as a teaching tool to illustrate the importance of data visualization. python animation simulated-annealing summa...

sidetable uses the pandas DataFrame accessor api to add a .stb accessor to all of your DataFrames. Once you import sidetable you are ready to go. In these examples, I will be using seaborn's Titanic dataset as an example but seaborn is not a direct dependency....
