Python: Day of Week How to Calculate

Day of the week you can find in two ways. One is from Calendar, and another one is from a function. Here, I have given my ideas on a better method. Also, the result you can get in a tuple. You might also like Attitude is Everything That Changes Your Life.

Day of Week and Day_Name

1. Monday 0
2. Tuesday 1
3. Wednesday 2
4. Thursday 3
5. Friday 4
6. Saturday 5
7. Sunday 6

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. Check out the best example to use this method.

Below is the output from the above logic

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 from a 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 assigned values. When you issue Print, 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.
