Creating a datetime Object

Obviously we need to learn how to work with timestamps that differ from current. Let's begin with creating datetime objects.

As you remember from the previous chapter, datetime object has 9 arguments. Let's show the necessary ones in the example below.

# Load class from library
from datetime import datetime

# Create new datetime object
datetime(year, month, day, hour, minute, second, microsecond, ...)

              
12345

            
# Load class from library
from datetime import datetime

# Create new datetime object
datetime(year, month, day, hour, minute, second, microsecond, ...)
copy

The first 3 arguments are required. Like for date object you are free to use either keyword, either positional arguments. For example, let's create datetime object with the following value: "November 17, 2017, 12:34:56".

# Load class from library
from datetime import datetime

# Create datetime object using keyword arguments
d = datetime(month = 11, year = 2017, day = 17, hour = 12, minute = 34, second = 56)
# Create datetime object using positional arguments
t = datetime(2017, 11, 17, 12, 34, 56)

# Check their values
print("Are", d, "and", t, "equal:", d == t)

              
12345678910

            
# Load class from library
from datetime import datetime

# Create datetime object using keyword arguments
d = datetime(month = 11, year = 2017, day = 17, hour = 12, minute = 34, second = 56)
# Create datetime object using positional arguments
t = datetime(2017, 11, 17, 12, 34, 56)

# Check their values
print("Are", d, "and", t, "equal:", d == t)
copy

Assign the date and the time "29 February, 2020, 19:48:23" to the variable t. Feel free to use either positional or keyword arguments.

Ratkaisu

# Load class from library
from datetime import datetime

# Create datetime object
t = datetime(day = 29, month = 2, year = 2020, hour = 19, minute = 48, second = 23)

# Print saved date and time
print("The saved date and time are:", t)
