Datetime Methods

datetime objects as it follows from the name contain both date and time. So, the methods we learned for date objects are also appliable to datetime objects. These methods are: .weekday(), .isoweekday() and .replace().

But since we expand date with time there have to be some new methods. For example, we can split datetime objects into date and time objects. In the previous chapter, we used .day, .minute and other methods to extract specific dimensions of a datetime object. These methods are:

  • datetime.date() - returns date of datetime object;

  • datetime.time() - returns time of datetime object;

# Load class from library
from datetime import datetime

# Create datetime object
dt = datetime(2010, 7, 5, 18, 30, 25)

# Extract month and day
print(f"date object extracted from dt: {dt.date()}")

# Extract hour and minute
print(f"time object extracted from dt: {dt.time()}")

              
1234567891011

            
# Load class from library
from datetime import datetime

# Create datetime object
dt = datetime(2010, 7, 5, 18, 30, 25)

# Extract month and day
print(f"date object extracted from dt: {dt.date()}")

# Extract hour and minute
print(f"time object extracted from dt: {dt.time()}")
