temporals 0.1.6

Python library providing time, date and datetime periods support

Temporals

The goal of this library is to provide a minimalistic, out-of-the-box utility on top of the Python's datetime in regards to working with time and date, or both, periods.

:warning: As it currently stands (assume the latest release), the library has no out of the box support for "aware" datetime objects. All the calculations are done by the Python datetime library.

Quickstart

Installation

You can either download the latest package from this repository or via pip:

pip install temporals

Periods

The library offers access to three different types of periods:

• TimePeriod

  The TimePeriod class allows you to define a period using datetime.time, and as such, is limited to just the 24 hours within a day.

• DatePeriod

  The DatePeriod class allows you to define a period using datetime.date and work with any dates within its bounds.

• DatetimePeriod

  This is the most complete implementation of both periods above as it contains both a date, and a time, defined using datetime.datetime.

Documentation

In-depth documentation available on the Wiki page of the repository - https://github.com/dimitarOnGithub/temporals/wiki

Examples

As mentioned above, you might find use for the different periods in different situations, let's look at the following TimePeriod example:

from datetime import time
from temporals import TimePeriod

workday = TimePeriod(start=time(8, 0), end=time(18, 0))
# Do you have an important call scheduled?
client_call = time(13, 0)
print(client_call in workday)  # True

# Or maybe you have an appointment and you want to see if it overlaps with your work hours?
appointment = TimePeriod(start=time(17, 30), end=time(18, 15))
appointment.overlaps_with(workday)  # True

# Let's see what's the overlap like, so you can plan accordingly
overlap = appointment.get_overlap(workday)  # get_overlap returns a TimePeriod
print(overlap)  # 17:30:00/18:00:00

---

Let's do something less day-to-day like, with this DatePeriod:

from datetime import date
from temporals import DatePeriod

time_off = DatePeriod(start=date(2024, 8, 1), end=date(2024, 8, 14))
# All roads lead to Rome
italy_visit = DatePeriod(start=date(2024, 8, 3), end=date(2024, 8, 10))

# I hope you have a good... how long again?
print(italy_visit.duration)  # P0Y0M1W0DT0H0M0S
# Wow, that sure is a mouthful, can we get it simplified?
print(italy_visit.duration.isoformat(fold=True))  # 'P1W'

---

Sometimes, we need both date and time to properly describe a period in time and this is the purpose DatetimePeriod serves

from datetime import datetime
from temporals import DatetimePeriod

takeoff = datetime(2024, 8, 2, 22, 11, 34)  # 22:11:34, 2nd of Aug 2024
landing = datetime(2024, 8, 3, 4, 55, 3)  # 04:55:03, 3rd of Aug 2024

flight = DatetimePeriod(start=takeoff, end=landing)
print(flight)  
# 2024-08-02T22:11:34/2024-08-03T04:55:03

# This is a PITA to read, why not try something nicer
print(flight.duration.isoformat())
# PT6H43M29S

# "Stop. Enhance. Give me a hard copy right there."
pattern = "%Hh%Mm"
formatted_time = flight.duration.format(pattern)
sentence = f"The flight lasted around {formatted_time}"
print(sentence)
# The flight lasted around 6h43m
