Pandas Practice Set-1: Find the number of rows and columns and data type of each column of diamonds Dataframe


5. Count Rows, Columns, and Data Types

Write a Pandas program to find the number of rows and columns and data type of each column 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("Number of rows and columns:")
print(diamonds.shape)
print("\nData type of each column:")
print(diamonds.dtypes)

Sample Output:

Number of rows and columns:
(53940, 10)

Data type of each column:
carat      float64
cut         object
color       object
clarity     object
depth      float64
table      float64
price        int64
x          float64
y          float64
z          float64
dtype: object
