Pandas Practice Set-1: Calculate the mean of price for each cut of diamonds DataFrame

Pandas Practice Set-1: Exercise-28 with Solution

Write a Pandas program to calculate the mean of price for each cut of 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("\nCalculate the mean of price for each cut:")
print(diamonds.groupby('cut').price.mean())

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
1   0.21  Premium     E     SI1   59.8   61.0    326  3.89  3.84  2.31
2   0.23     Good     E     VS1   56.9   65.0    327  4.05  4.07  2.31
3   0.29  Premium     I     VS2   62.4   58.0    334  4.20  4.23  2.63
4   0.31     Good     J     SI2   63.3   58.0    335  4.34  4.35  2.75

Calculate the mean of price for each cut:
cut
Fair         4358.757764
Good         3928.864452
Ideal        3457.541970
Premium      4584.257704
Very Good    3981.759891
Name: price, dtype: float64
