How to convert a number to its correlating day of the week?
Question:
How do I convert a number to its correlating day of the week?
For example:
def string(hour_of_day, day_of_week, date) :
print(f'{day_of_week} {date} at hour {hour_of_day}')
how can I re-write the ‘day_of_week’ part in print so that when I use the function:
string(12, 1, '2020/02/18')
How can I get Tuesday 2020/02/18 at hour 12 instead of 1 2020/02/18 at hour 12?
Answers:
Use a dictionary along the lines of
daysdict = { 1: 'Monday', 2: 'Tuesday'} exetended for all the days
then access using daysdict[1]
Although your day 1 seems to be Tuesday!
It is possible to get the day directly from the date itself – something for you to check out.
Use calendar module
If you have already the weekday number, do:
import calendar
day_of_week = 1
calendar.day_name[day_of_week]
## 'Tuesday'
The calendar module is always available in Python (it is belongs to the inbuilt standard modules).
So the dictionary {0: "Monday", 1: "Tuesday", ...} is already defined as calendar.day_name. So no need to define it yourself. Instead type import calendar and you have it available.
Use datetime module to get weekday directly from the date
from datetime import datetime
def date2weekday(date):
return datetime.strptime(date, "%Y/%m/%d").strftime('%A')
def myfunction(hour_of_day, date):
return f"{date2weekday(date)} {date} at hour {hour_of_day}"
myfunction(12, '2020/02/18')
## 'Tuesday 2020/02/18 at hour 12'
You can use the strftime method from a datetime object:
import datetime
print(datetime.datetime(2022, 10, 21).strftime('%A %Y/%m/%d'))
It will give you this answer:
Friday 2022/10/21
To adapt it to your solution just do this:
from datetime import datetime
def string(hour_of_day, date):
print(f'{date.strftime('%A %Y/%m/%d')} at hour {hour_of_day}')
string(12, datetime(year=2022, month=10, day=21))
The good thing about this solution is that you don’t need to know the day of the week of a date, Python already knows that, just ask him 😉
