Python Pandas Dataset Analysis: Sorting & More 📊

Using Python's Pandas package (Free!) to better understand a dataset. Saniya will be covering how to load in pandas, read in a dataset to a jupyter notebook, and do other key pandas dataset operations, such as: sorting (based on 1 or more columns), subsetting (selecting certain rows based on criteria), looking for unique elements in pandas columns, finding value counts, and beyond! This is an initial exploration into working with pandas to better understand data. Saniya also works with a deforestation dataframe "annual-change-forest-area.csv" from Kaggle ( https://www.kaggle.com/chiticariucristian/deforestation-and-forest-loss) in support of efforts to improving climate change outcomes and reducing deforestation (So the real pandas and other critters can have their forest homes preserved!).
Saniya talks a little bit about how to get datasets to practice on (for learning or for competitions on crowd-sourcing sites like kaggle.com)
Please reach out to Saniya with any and all questions you have and please subscribe to Saniya's YouTube channel for more updates :)

In short, we will learn how to use Python's Pandas to better understand deforestation datasets (so we can eventually help protect Panda homes)). Please note this is for Python 3.

Please note Saniya plans to hopefully make more Python videos. Here, we learn Python Pandas tools like:
* import pandas as pd (nickname for pandas)
* import numpy as np
* reading in a dataset (csv file) to pandas
* get # of columns and rows for dataset
* view first 5 rows (head of dataset)
* sort dataframes based on columns
* extract columns from a dataframe
* look for and retrieve all unique elements in columns
* finding value counts (# of times each item appears in a pandas column)
* subsetting dataframe based on criteria ( relational operators and .isin()).
* and beyond!
