The feature to run the __main__ module of a package when using the command line -m option was introduced in Python 2.7. For 2.6 you need to specify the package module name to run; -m test.__main__ should work. See the documentation here.
To understand what modules can do for you, read this: https://learn.microsoft.com/en-us/powershell/scripting/developer/module/writing-a-windows-powershell-module?view=powershell-7.1 In a nutshell, Windows PowerShell modules allow you to partition, organize, and abstract your Windows PowerShell code into self-contained, reusable units. With these reusable units, administrators, script developers, and cmdlet developers can easily share their modules directly with others. Script developers can also repackage … Read more
Your understanding is correct: the only difference is that ifilter returns an iterator, while using filter is like calling: list(ifilter(…)) You may also be interested in what PEP 289 says about filter and ifilter: List comprehensions greatly reduced the need for filter() and map(). Likewise, generator expressions are expected to minimize the need for itertools.ifilter() … Read more
Use: module FooLib end module FooLib::Plugins end class FooLib::Plugins::Plugin; end #the base for plugins class FooLib::Plugins::Bar < FooLib::Plugins::Plugin; end class FooLib::Plugins::Bar2 < FooLib::Plugins::Plugin; end or in a different words: module FooLib module Plugins class Plugin; end #the base for plugins class Bar < Plugin; end class Bar2 < Plugin; end end end Also arrange the … Read more
In general a module should be a collection of packages. But still you can create modules of single packages. As Volker said, this might only make sense, if you want these packages to have a different lifecycle. It could also make sense, when you want to import these modules from another project and don’t want … Read more
Yes, but it’ll only work as expected with fully qualified access paths to modules: import example example.examplemod.config.CONSTANT = “Better value” example.examplemod.do_stuff()
In the first example, it defines the Parent module and then the Child module. The second example, as you say yourself, must have the Parent module defined before hand. At the expense of one more line of code, you ensure that the module that you’re nesting under by using your first example is always going … Read more
Check out Module::ScanDeps and the “scandeps.pl” utility that comes with it. It can do a static (and recursive) analysis of your code for dependencies as well as the %INC dump either after compiling or running the program. Please note that the static source scanning always errs on the side of including too many dependencies. (It … Read more
For development, I install my own Perl and leave the system Perl alone. If I want to upgrade the system Perl, I use the system package manager. For my development Perl, I use the cpan tool. Since I keep those separate, I should never mess up the Perl that the system needs for its maintenance … Read more
Modules in Ruby aren’t really that special, so you can just assign them to another constant: [4] (pry) main: 0> module TestModule [4] (pry) main: 0* def self.foo [4] (pry) main: 0* “test” [4] (pry) main: 0* end [4] (pry) main: 0* end => nil [5] (pry) main: 0> tm = TestModule => TestModule [6] … Read more
