Pandas Practice Set-1: Sort the entire diamonds DataFrame by the 'carat' Series in ascending and descending order
14. Sort Entire DataFrame by 'carat' in Ascending and Descending Order
Write a Pandas program to sort the entire diamonds DataFrame by the 'carat' Series in ascending and descending order.
Sample Solution :
Python Code :
import pandas as pd
diamonds = pd.read_csv('https://raw.githubusercontent.com/mwaskom/seaborn-data/master/diamonds.csv')
print("Original Dataframe:")
print(diamonds.head())
print("\nSort the entire diamonds DataFrame by the 'carat' Series in ascending order")
result = diamonds.sort_values('carat')
print(result)
print("\nSort the entire diamonds DataFrame by the 'carat' Series in descending order")
result = diamonds.sort_values('carat', ascending=False)
print(result)
Sample Output:
Original Dataframe:

- Write a Pandas program to sort the diamonds DataFrame by the 'carat' column in ascending order and display the result.
- Write a Pandas program to sort the diamonds DataFrame by 'carat' in descending order and verify by printing the first 10 rows.
- Write a Pandas program to sort the DataFrame by 'carat' in both orders and then merge the results into a single DataFrame for comparison.
- Write a Pandas program to sort by 'carat' first in ascending order then in descending order, and finally compute the difference in the top values.
