The naming convention. It’s obviously better to have any than none. As I was writing, I noticed that the title doesn’t reflect what I wrote. All turned out to be not about convention, but about comparing PHP to Python. Personally none of the languages is my favorite.
After reading the whole post, I realized that Python is not better than PHP, it is messed the same way, so why bother changing from PHP to Python?
In Python blocks have to be indented just because the indentation level defines the logic. In C/C++/Java there are { and } while in Ruby there is begin and end. Of course indenting is helpful. Just like syntax coloring in editor.
In Ruby you can do whatever you want with the indentation. That’s not a problem. Every good editor can fix the code layout due to some rules. Normally I use VIM for all those scripting languages, for programming in Ruby and Python too. In VIM after opening any file I can do the magic command:
There are some numbers and units. Numbers are numbers. Units are units. Numbers informs how many. Units inform about two things:
Unfortunately it seems like most programmers just don’t care about all that stuff.
Here is a newer version of this virtualenv tutorial.
Virtualenv is a great piece of software. It allows to create virtual environments. Each of them can have a different version of Python and different sets of libraries.
While creating this tutorial I used following tools and versions:
As usually: it depends. Normally you can create and use Python programs without that, but using virtual environments can help a lot.
Such a virtual environment provides many possibilities such as:
I found this on the Ovid’s blog.
First of all: this is quite a nice writing of something called the modern perl. Everybody who shouts that perl is a piece of shit should read it. YES, you can write a nice looking code in perl. Code that is maintainable, and is easy to read. And is objective (a kind of somewhat different langauge syntax but who cares. Each language is different and has different class definitions - consider Ada, Perl, C++ and Python).
Some ideas about the testing solution. Of course this is PostgreSQL :).
