To combine and sort a dataset using Pandas in Python, follow these steps:

  1. Import the pandas library:
import pandas as pd 
  1. Load the datasets that you want to combine into separate pandas dataframes:
df1 = pd.read_csv("dataset1.csv")
df2 = pd.read_csv("dataset2.csv")
  1. Use the pandas combine function to combine the two dataframes:
df = pd.concat([df1, df2])
  1. Sort the combined dataframe by a specific column (for example, alphabetically by name):
df = df.sort_values(by=["Name"])
  1. Save the sorted dataframe to a new CSV file:
df.to_csv("sorted_dataset.csv", index=False)

Additionally, you can also use the pandas merge function to combine two dataframes based on a specific column that they share in common.
