 Amazon Relational Database Service (AWS RDS) makes it easy to set up, operate, and scale a relational database in the cloud.

Python: Day of Week How to Calculate

1. Python Logic to get Day of Week from Calendar


from datetime import datetime
import calendar
dt = datetime.today()
dn = dt.weekday()

print("Today is day number: {0}".format(dn))
print("Today is a {0}".format(calendar.day_name[dn]))


Here, the print uses string.format method to print output.


The Output

Python: Day of Week How to Calculate
The result from the first logic


Instead of directly using DateTime, you can write a function - that creates a tuple with Day of week and Day name.

2. Python Logic to get Day and Day_name 

User defined function

from datetime import datetime
from datetime import timedelta
import calendar
def DayOfWeek(d=None):
if d == None:
d = datetime.today()
dn = d.weekday()
return (dn, calendar.day_name[dn])

print(DayOfWeek())
d2 = datetime.today() + timedelta(1)
print(DayOfWeek(d2))


Here, DayOfWeek is a function. You assigned None to d. In the IF, for 'd' and 'dn', you have assigned values. When you Print executes, it returns two values as a tuple.

An object is simply a collection of data (variables) and methods (functions) that act on those data. Similarly, a class is a blueprint for that object.

The Output

Day of week
The result from the second logic
