TimePeriods

A Python lib intended to handle operation on time periods (ie periods from one datetime.datetime to another).

It includes simple set operation like intersection and union.

Models

This lib mainly include two classe :

TimePeriod

Describes an immutable period, having

• begin (datetime.datetime) : the beginning of the period (included)
• end (datetime.datetime) : the end of the period
• | (or +) : operator returning the union of two TimePeriod
• & : operation returning the intersection of two TimePeriod

TimePeriodSet

A set of TimePeriod usable as an iterable, and indexable, with

• periods : the list of contained TimePeriod
• | (or +) : operator returning the union of all TimePeriod in two TimePeriodSet, or the union of a TimePeriodSet and a TimePeriod
• & : operator returning all the intersections between the TimePeriod of two TimePeriodSet, or a TimePeriodSet and a single TimePeriod

Exceptions

InvalidPeriodException

Raised only when trying to create an incoherent TimePeriod, ie one in which the beginning is equal or later than the end.

SeparatePeriodsException

Raised when an operation has been made between two TimePeriod without any intersection.
