For example, on July 5, 2010, I would like to calculate the string
July 5, 2010
How should this be done?

You can use the datetime module for working with dates and times in Python. The strftime method allows you to produce string representation of dates and times with a format you specify.
>>> import datetime
>>> datetime.date.today().strftime("%B %d, %Y")
'July 23, 2010'
>>> datetime.datetime.now().strftime("%I:%M%p on %B %d, %Y")
'10:36AM on July 23, 2010'

I found this to be a helpful reference when trying to make different custom formats: strftime.org
#python3
import datetime
print(
'1: test-{date:%Y-%m-%d_%H:%M:%S}.txt'.format( date=datetime.datetime.now() )
)
d = datetime.datetime.now()
print( "2a: {:%B %d, %Y}".format(d))
# see the f" to tell python this is a f string, no .format
print(f"2b: {d:%B %d, %Y}")
print(f"3: Today is {datetime.datetime.now():%Y-%m-%d} yay")
#4: to make the time timezone-aware pass timezone to .now()
tz = datetime.timezone.utc
ft = "%Y-%m-%dT%H:%M:%S%z"
t = datetime.datetime.now(tz=tz).strftime(ft)
print(f"4: timezone-aware time: {t}")
1: test-2018-02-14_16:40:52.txt
2a: March 04, 2018
2b: March 04, 2018
3: Today is 2018-11-11 yay
4: timezone-aware time: 2022-05-05T09:04:24+0000
Description:
Using the new string format to inject value into a string at placeholder {}, value is the current time.
Then rather than just displaying the raw value as {}, use formatting to obtain the correct date format.

what does
f mean in print(f"3?
Pieter
@lei-yang here is a explanation: realpython.com/python-f-strings it marks the string as f string, and python then looks for { } with code/variables in it, and places the content in the string. It is the latest python3.6 string formatting addition

The bottom of this page https://docs.python.org/3/library/datetime.html lists the placeholders like
%B and what they represent.>>> import datetime
>>> now = datetime.datetime.now()
>>> now.strftime("%B %d, %Y")
'July 23, 2010'

If you don't care about formatting and you just need some quick date, you can use this:
import time
print(time.ctime())
Comments
With time module:
import time
time.strftime("%B %d, %Y")
>>> 'July 23, 2010'
time.strftime("%I:%M%p on %B %d, %Y")
>>> '10:36AM on July 23, 2010'

Simple
# 15-02-2023
datetime.datetime.now().strftime("%d-%m-%Y")
and for this question use "July 5, 2010"
# July 5, 2010
datetime.datetime.now().strftime("%B %d, %Y")

That's not the format requested in the question, is it?
