Pandas Practice Set-1: Remove multiple rows at once from diamonds dataframe

Pandas Practice Set-1: Exercise-11 with Solution

Write a Pandas program to remove multiple rows at once (axis=0 refers to rows) from diamonds dataframe.

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("\nRemove multiple rows:")
diamonds.drop([2, 4, 5], axis=0, inplace=True)
print(diamonds.head())

Sample Output:

Original Dataframe:
   carat      cut color clarity  depth  table  price     x     y     z
0   0.23    Ideal     E     SI2   61.5   55.0    326  3.95  3.98  2.43
