8. Extract Date Components from UFO Reporting Date

Write a Pandas program to extract year, month, day, hour, minute, second and weekday from unidentified flying object (UFO) reporting date.

Sample Solution :

Python Code :

import pandas as pd
df = pd.read_csv(r'ufo.csv')
df['Date_time'] = df['Date_time'].astype('datetime64[ns]')
print("Original Dataframe:")
print(df.head())
print("\nYear:")
print(df.Date_time.dt.year.head())
print("\nMonth:")
print(df.Date_time.dt.month.head())
print("\nDay:")
print(df.Date_time.dt.day.head())
print("\nHour:")
print(df.Date_time.dt.hour.head())
print("\nMinute:")
print(df.Date_time.dt.minute.head())
print("\nSecond:")
print(df.Date_time.dt.second.head())
print("\nWeekday:")
print(df.Date_time.dt.weekday_name.head())

Sample Output:

2 1955-10-10 17:00:00  chester (uk/england)     ...      53.200000   -2.916667

4 1960-10-10 20:00:00               kaneohe     ...      21.418056 -157.803611
