Pandas Datetime: Check the empty values of UFO Dataframe

Pandas Datetime: Exercise-19 with Solution

Write a Pandas program to check the empty values of UFO (unidentified flying object) Dataframe.

Sample Solution:

Python Code:

import pandas as pd
df = pd.read_csv(r'C:\Users\rg\Downloads/ufo.csv')

Sample Output:

Date_time                          0
city                               0
state/province                     0
country                            0
UFO_shape                          0
length_of_encounter_seconds        0
described_duration_of_encounter    0
description                        0
date_documented                    0
latitude                           0
longitude                          0
dtype: int64
