Dates, Times and Clocks in Python
Learn it Cold

Dates, Times and Clocks in Python is a comprehensive Spaced Repetition System (SRS) flashcard deck for learning how to work with the Python datetime and time modules.

A substantial and growing body of research shows SRS to be the most effective way to learn. Nothing else comes close.

What You Will Learn

If you thought Python string generation was a PITA, working with dates and times might just make you cry.

The Python Dates, Times and Clocks deck builds the understanding that you desperately seek. This deck will teach you:

the date and time concepts on which the modules are built
when/where/why/how to use (or not use) each object type
how to convert date and time objects between different types/representations

The deck contains over 500 SRS flashcards, organized in 5 "chapters":

01) datetime Classes and Constructors
02) datetime Objects
03) Date and Time Strings
04) Time Zones
05) The time Module

This deck is targeted at Python v3. But differences from Python v2 are highlighted where they are likely to be encountered in common practice.

You won't learn to love these modules. But you will get comfortable using them.

Actual Questions

Chapter 1 - datetime Classes

While datetime.date, datetime.time and datetime.datetime objects each represent a point in time, a {{datetime.timedelta}} object represents a {{duration, or amount of time}}

Chapter 2 - datetime Objects

Point in time datetime objects (datetime.datetime, datetime.date and datetime.time) all have a {{replace()}} method that returns a new object of the same type, but with one or more of the attributes changed

Chapter 3 - Date and Time Strings

The {{datetime.datetime.strptime()}} class method can be considered to be the inverse of the {{strftime()}} object methods

Chapter 4 - Time Zones

It is considered best practice in Python to only work with non-UTC timezones when {{generating output to be read by humans}}

Chapter 5 - time Module

The time module functions for measuring elapsed time each operate on one of two notions of time - {{wall clock}} time, or {{CPU}} time

How You Will Learn

SRSoterica spaced repetition flashcard decks are an exciting breakthrough in learning concept-intensive subjects via SRS. All of our decks teach you:

essential concepts and functionality
in the right order
at the right level of detail
idiomatically - Pythonically

Our decks are comprehensive (without being exhaustive). They highlight the quirks that trip people up. They hammer home difficult concepts using multiple representation techniques, and layers of reinforcement.

Our decks are not just a set of facts. You get tested on your ability to apply what you learn. You analyze and evaluate the kinds of situations that you will encounter in everyday programming.

Our decks encompass the expertise and experience of multiple practicing professional programmers.

You will learn the subject cold.

Textbook Depth, Flashcard Efficiency!

Our decks combine the best features of a book:

comprehensive coverage
structured content
progressive learning

with the killer features of a flashcard deck:

concise presentation
testing and repetition

Learn effectively at any time, whether you've got two minutes or twenty.

Who Is This For?

This deck is targeted to intermediate Python programmers. It expects that you are reasonably comfortable with the language, in general, and that you already have a good understanding of:

OOP - classes, objects and methods
the structure and usage of modules and packages
exceptions

If you don't already understand these things, you should bone up elsewhere before you tackle this. You might also consider using the Python Essentials deck, as these are pretty fundamental things that should be known to any intermediate Python programmer.

100% Money Back Guarantee

There's not a better way than SRS to learn - really learn - the concepts and intricacies of the Python programming language.

Nobody else understands how to make concept-intensive SRS decks as well as we do. Nobody even comes close.

If you're not satisfied, you can have your money back.
