I'm gonna explain what's the function of pandas? well, let's begin...
This Pandas function application is used to apply a function to DataFrame, that accepts and returns only one scalar value to every element of the DataFrame. It is a Data-centric method of applying functions to DataFrames.
- Fast and efficient DataFrame object with the default and customized indexing.
- Tools for loading data into in-memory data objects from different file formats.
- Data alignment and integrated handling of missing data.
- Reshaping and pivoting of data sets.
And Pandas is one of the tools in Machine Learning which is used for data cleaning and analysis. It has features that are used for exploring, cleaning, transforming, and visualizing from data. ... It provides fast, flexible, and expressive data structures.
I can say, Pandas is hands down one of the best libraries of python. It supports reading and writing Excel spreadsheets, CVS's, and a whole lot of manipulation. It is more like a mandatory library you need to know if you're dealing with datasets from excel files and CSV files. i.e for Machine learning and data science.
