Pandas
Pandas complements the previously mentioned libraries with a special structure, called DataFrame, and also adds many statistical and data mangling methods, such as I/O, for many different formats, such as slicing, subsetting, handling missing data, merging, and reshaping, among others.
The DataFrame object is one of the most useful features of the whole library, providing a special 2D data structure with columns that can be of different data types.
