Q1- What is Python pandas?
Ans- Pandas is a Python software package that is mostly used to analyze and work with data. Wes Mckinney created a cross-platform, open-source library that was made available in 2008. This library provides methods and data structures for working with time-series and numerical information. Pandas may be set up via pip or the Anaconda package. With the help of this package, doing machine learning functions on the table data is simple and rapid. a little bit of body text
It offers capabilities for importing data into in-memory data objects from a variety of file types and is quick and effective at processing the data using its DataFrame object.
Q2-Describe the primary features of the Python pandas?
It contains features for sophisticated indexing, label-based slicing, and subsetting of big data sets.
Ans- Some of the major features of Python Pandas are:-
It performs well when combining and merging data.
It has features that let you reshape and pivot data collections.
Time Series functionality is included.
It offers joining and merging capabilities for data sets.
Series:
This three-dimensional data structure uses heterogeneous data storage.
Ans-The many types of data structures offered by Pandas include:
Rows and columns make up the tabular data structure known as a “DataFrame.” Data and size might change in this situation.
Q3-Describe different types of Data Structures available in Pandas?
Panel:
A homogenous, one-dimensional array data structure that is unchanging in size. DataFrame:
Q5-What is use of Reindexing in pandas?
Ans-A one-dimensional array data structure called a series may contain any kind of data. In an Excel sheet, it is the columns that contains a sequence of data of a single kind. The axial identifiers of the dataset are referred to as the index in this straightforward Pandas data structure.
Ans-The DataFrame’s row and column labels are changed by reindexing. It adjusts to the facts so that it matches a specific set of keywords along a specific axis. Additionally, the label places where there are no data are updated to include the missing value marker.
Q4- What is Series in Pandas?
Q7-
Q6- What is Data Frame in Pandas?
Ans-A computational approach to Matplotlib is provided by the Pylab module of the Matplotlib package. An object-oriented charting library is Matplotlib. It combines the NumPy module for graphical plotting with the Matplotlib library. This is a part of Matplotlib rather than being a standalone module, giving users a matplotlib-like experience.
Ans-Pandas has a data structure called DataFrame that allows for the storage of mixed, two-dimensional, size-mutable data tables with labelled rows and columns. It is arranged in relational database like a table. The rows and columns of this construct can be subjected to a mathematical operations. The data type for each column in this case will be the same.
