2. Modify Default Column Values and Print First 6 Rows

Write a Pandas program to read a dataset from diamonds DataFrame and modify the default columns values and print the first 6 rows.

Sample Solution :

Python Code :

import pandas as pd
user_cols = ['carat', 'cut', 'x', 'y', 'z']
diamonds = pd.read_csv('https://raw.githubusercontent.com/mwaskom/seaborn-data/master/diamonds.csv')
print("First 6 rows:")
print(diamonds[user_cols].head(6))

Sample Output:

First 6 rows:
   carat        cut     x     y     z
0   0.23      Ideal  3.95  3.98  2.43
1   0.21    Premium  3.89  3.84  2.31
2   0.23       Good  4.05  4.07  2.31
3   0.29    Premium  4.20  4.23  2.63
4   0.31       Good  4.34  4.35  2.75
5   0.24  Very Good  3.94  3.96  2.48
