Pandas Practice Set-1: Count the number of missing values in each Series of diamonds DataFrame
Write a Pandas program to count the number of missing values in each Series 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("\nNumber of missing values in each Series of diamonds DataFrame:")
print(diamonds.isnull().sum())
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 Number of missing values in each Series of diamonds DataFrame: carat 0 cut 0 color 0 clarity 0 depth 0 table 0 price 0 x 0 y 0 z 0 dtype: int64

Previous: Write a Pandas program to create a DataFrame of booleans (True if missing, False if not missing) from diamonds DataFrame.
Next: Write a Pandas program to check the number of rows and columns and drop those row if 'any' values are missing in a row of diamonds DataFrame.
