  • Python Success Stories

    ...shell scripts, and also sizeable enterprise systems deployed across the university. By using it on a number of projects, we have come to understand that Python's dynamic nature, support for high-level data structures, and easy object-orientation all lower the barrier to writing well-structured reusable code in less time. The language's clear and simple syntax helps to reveal the sense (or otherwise!) of our code. This makes it easier to understand and reason about code during development and - m...

  • Foreword for "Programming Python" (1st ed.)

    ...shell and C instead! (Yes, I borrowed from C too, but only its least controversial features, in my desire to please the Unix/C audience.) Any individual creation has its ideosyncracies, and occasionally its creator has to justify these. Perhaps Python's most controversial feature is its use of indentation for statement grouping, which derives directly from ABC. It is one of the language's features that is dearest to my heart. It makes Python code more readable in two ways. First, ...

  • PEP 502 -- String Interpolation - Extended Discussion

    ...shell interpolation syntax, with safe-substitution feature, that finds its main use cases in shell and internationalization tools: Template('Hello, user: $user, id: ${id}, on host: $hostname').substitute(params) While also verbose, the string itself is readable. Though functionality is limited, it meets its requirements well. It isn't powerful enough for many cases, and that helps keep inexperienced users out of trouble, as well as avoiding issues with moderately-trusted input (i18n) from thir...

  • PEP 405 -- Python Virtual Environments

    ...shell activation scripts" for POSIX and Windows systems in the bin or Scripts directory of the venv. These scripts simply add the virtual environment's bin (or Scripts) directory to the front of the user's shell PATH. This is not strictly necessary for use of a virtual environment (as an explicit path to the venv's python binary or scripts can just as well be used), but it is convenient. In order to allow pysetup and other Python package managers to install packages into the virtual environment...

Although a very useful tool, PyDoc has several deficiencies, including: In the case of the GUI/HTML, except for some heuristic hyperlinking of identifier names, no formatting of the docstrings is done.

PyDoc extracts docstrings and structural information (class identifiers, method sig...

Comparison to PEP 215 PEP 215 describes an alternate proposal for string interpolation. Unlike that PEP, this one does not propose any new syntax for Python. All the proposed new features are embodied in a new library module. PEP 215 proposes a new string prefix representation such as $"" which signal to Python that a ...

This popularity suggests it may be a valuable addition to the Python libraries. Why aren't getopt and optparse enough? One argument against adding argparse is that there are "already two different option parsing modules in the standard library" [9]. The following is a list of features provided by argparse but not present in getopt or optpars...
