pandas is part of the Anaconda distribution and can be
installed with Anaconda or Miniconda:
conda install pandas
pandas can be installed via pip from PyPI.
pip install pandas

Straight to tutorial…
When working with tabular data, such as data stored in spreadsheets or databases, pandas is the right tool for you. pandas will help you
to explore, clean and process your data. In pandas, a data table is called a DataFrame.
To introduction tutorial
To user guide
pandas supports the integration with many file formats or data sources out of the box (csv, excel, sql, json, parquet,…). Importing data from each of these
data sources is provided by function with the prefix read_*. Similarly, the to_* methods are used to store data.
Selecting or filtering specific rows and/or columns? Filtering the data on a condition? Methods for slicing, selecting, and extracting the
data you need are available in pandas.
pandas provides plotting your data out of the box, using the power of Matplotlib. You can pick the plot type (scatter, bar, boxplot,…)
corresponding to your data.
There is no need to loop over all rows of your data table to do calculations. Data manipulations on a column work elementwise.
Adding a column to a DataFrame based on existing data in other columns is straightforward.
Basic statistics (mean, median, min, max, counts…) are easily calculable. These or custom aggregations can be applied on the entire
data set, a sliding window of the data or grouped by categories. The latter is also known as the split-apply-combine approach.
Change the structure of your data table in multiple ways. You can melt() your data table from wide to long/tidy form or pivot()
from long to wide format. With aggregations built-in, a pivot table is created with a single command.
Multiple tables can be concatenated both column wise as row wise and database-like join/merge operations are provided to combine multiple tables of data.
pandas has great support for time series and has an extensive set of tools for working with dates, times, and time-indexed data.
Data sets do not only contain numerical data. pandas provides a wide range of functions to clean textual data and extract useful information from it.
Are you familiar with other software for manipulating tablular data? Learn
the pandas-equivalent operations compared to software you already know:
The R programming language provides the dataframe data structure and multiple packages,
such as tidyverse use and extend data.frames for convenient data handling
functionalities similar to pandas.
Already familiar to SELECT, GROUP BY, JOIN, etc.?
Most of these SQL manipulations do have equivalents in pandas.
The data set included in the
STATA statistical software suite corresponds
to the pandas dataframe. Many of the operations known from STATA have an equivalent
The SAS statistical software suite
also provides the data set corresponding to the pandas dataframe.
Also SAS vectorized operations, filtering, string processing operations, and more have similar
functions in pandas.
