15. Filter Rows with Carat Weight at Least 0.3

Write a Pandas program to filter the DataFrame rows to only show carat weight at least 0.3.

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(20))
print("\nRows to only show carat weight at least 0.3:")
booleans = []
for w in diamonds.carat:
   if w >= .3:
       booleans.append(True)
   else:
       booleans.append(False)
print(booleans[0:20])

Sample Output:

Original Dataframe:
