It can be a real pain to upload huge files. Many services limit their upload sizes to a few megabytes, and you don’t want a single connection open forever either. The super simple way to get around that is simply send the file in lots of small parts, aka chunking. Finished code example can be … [Read more…]
Dealing with communications across programs, processes or even threads can be a real pain in the patella. Each situation usually calls for something slightly different and has to work with a limited set of options. On top of that, a lot of tutorials I see are people simply starting one program from inside the other (for … [Read more…]
Thread and Multiprocessing Pools are an underused feature of Python. In my opinion, they are the easiest way to dip your feet into concurrency, and yet still the method I use most often. They allow you to easily offload CPU or I/O bound tasks to a pre-instantiated group (pool) of threads or processes. One of … [Read more…]
This month is my wife’s, mother’s and my own birthday, all within a span of nine days. What are the odds of that? No idea, I’m no statistician. However, as a developer, I thought it would be fun to prove (or disprove?) the Birthday Paradox with some Python coding. If you haven’t heard of … [Read more…]
Spice up your code with wrappers! In Python, a wrapper, also known as a decorator, is simply encapsulating a function within other functions.
| 1 2 3 4 5 6 7 | @wrapper def my_func(a, b=2): print(b) @meta_decorator(foo="bar") def my_other_func(**kwargs): print(kwargs) |
In Reusables, all the wrappers take arguments, aka meta decorators, so you will at minimum have to end them with parens ()s. Let’s take a look at the one I use … [Read more…]
As I sit here, anxious for the new AMD Vega 64 to be released, I decide to keep myself busy writing some Python code….designed to text me as soon as a new “rx vega 64” search term showed up on Amazon (I have the patience of a child on Christmas Eve, so sue me.) When … [Read more…]
Is Python more suited for EAFP or LBYL coding styles? It has been debated across message boards, email chains, stackoverflow, twitter and workplaces. It’s not as heated as some other battles; like how spaces are better than tabs, or that nano is indisputably the best terminal editor ; but people seem to have their own … [Read more…]
Boring Background I have always had in interest in making a local photo organization tool, that supports albums and tagging the way I want to do it. Maybe down the line allowing others to connect and use it too. So I started on one a few years ago, using what I knew best, Python REST … [Read more…]
Box has surpassed my expectations in popularity, even appearing in the Python Weekly newsletter and on Python Bytes podcast. I am very grateful for everyone that uses it and hope that you find it to be another great tool in your Python tool-belt! Also a huge shot out to everyone that has provided feedback or code … [Read more…]
Often times in python there comes a need to have multiple functions act in a similar manner. It could be anything from making sure that similar functions output the right type of result, they all log when they are called or all report exceptions in the same way. An easy and repeatable way to accomplish … [Read more…]
