Generate random date in ISO date time format yyyy-MM-dd'T'HH:mm:ss. SSSXXX-CodePudding

It's my first time working with dates in Python. I am trying to generate a random date within a range in python the date format should be: yyyy-MM-dd'T'HH:mm:ss.SSSXXX timezone for example, "2022-10-31T01:30:00.000 05:00"

I also need to add an hour integer to the generated date, I am simulating a flight, so the first date is the departure and the second one the landing date.

This is basically two different questions which you can join to get your result. I'm assuming you already have datetime objects.

Get a random date

You could generate a random date using an answer from another question:

from random import randrange
from datetime import timedelta

def random_date(start, end):
    """
    This function will return a random datetime between two datetime 
    objects.
    """
    delta = end - start
    int_delta = (delta.days * 24 * 60 * 60)   delta.seconds
    random_second = randrange(int_delta)
    return start   timedelta(seconds=random_second)

which receives two datetime objects.

Usage:
d1 = datetime.strptime('1/1/2008 1:30 PM', '%m/%d/%Y %I:%M %p')
d2 = datetime.strptime('1/1/2009 4:50 AM', '%m/%d/%Y %I:%M %p')

random_date(d1, d2)

Display date on desired format

You need to use .isoformat().

datetime(2019, 5, 18, 15, 17, 0, 0, tzinfo=timezone.utc).isoformat()

Output:

2019-05-18T15:17:00 00:00

Something like this

from datetime import datetime,tzinfo,timedelta
from faker import Faker


class simple_utc(tzinfo):
    def tzname(self,**kwargs):
        return "UTC"
    def utcoffset(self, dt):
        return timedelta(0)


fake=Faker()
#define your range
randomdate=fake.date_time_between(start_date="-1d", end_date="now")
#add an hour
randomdatePlusHour=randomdate timedelta(hours=1)

print(randomdate.replace(tzinfo=simple_utc()).isoformat(),randomdatePlusHour.replace(tzinfo=simple_utc()).isoformat())

with the prerrequisit of faker (pip install faker).
