Descriptive Statistical Measures of a DataFrame
The describe() function outputs descriptive statistics which include those that summarize the central tendency, dispersion, and shape of a dataset’s distribution, excluding NaN values. For numeric data, the result’s index will include count, mean, std, min, and max as well as lower, 50, and upper percentiles. For object data (e.g. strings), the result’s index will include count, unique, top, and freq.

Data Processing with Pandas
Data Processing is an important part of any task that includes data-driven work. It helps us to provide meaningful insights from the data. As we know Python is a widely used programming language, and there are various libraries and tools available for data processing.
In this article, we are going to see Data Processing in Python, Loading, Printing rows and Columns, Data frame summary, Missing data values Sorting and Merging Data Frames, Applying Functions, and Visualizing Dataframes.
