The csv module in Python 2.7 is more-or-less hard-wired to work with ASCII and only ASCII.

Sadly, we're often confronted with CSV files that include Unicode characters. There are numerous Stack Overflow questions on this topic. http://stackoverflow.com/search?q=python+csv+unicode

What to do? Since csv …

Brilliant. Thank you for this.

Too many of the questions on StackOverflow that include multi-threading are better approached as multi-processing. In Linux, there are times when all threads of a single process are stopped while the process (as a whole) waits for system …

A common (and small) task is reformatting a file that's in some variant of CSV. It could be a SQL database extract, or an export from an application that works well with CSV files.

In Python 2.x, a CSV file with Unicode was a bit of a problem. The …

Some folks love the twin ideas that (1) "someone" might break the API rules and (2) they must write lots of bonus code to "prevent" problems.

Sigh.

There are three distinct things here.

• API definition - something we do all the time.
• "Defensive Programming" - something that may or may not actually …

Read this: "Here Comes Functional Programming" by Larry O'Brien in SD Times.

people who should know better continue to assert that statically typed languages are "safer, because the compiler can catch errors that otherwise wouldn't show up until runtime." While it's true a statically typed language can detect that you've …

Emphasis on the "More On" as in "Moron". This is a standard design error story. The issue is that inheritance happens along an "axis" or "dimension" where the subclasses are at different points along that axis. Multi-dimensional inheritance is an EPIC FAIL.

The topic of VMware came up at my local 757 Python Users Group.

A common administrative need is to control VM farms. While there are a number of pointy-clicky GUI tools, VMware offers the VIX library to permit writing scripts to control VM's.

Here's some information we looked at recently …

In Command-Line Applications, we looked at a Python main-import switch which boiled down to this.

for file in args.file:
    with open( file, "r" ) as source:
        process_file( source, args )

The point was that each distinct file on the command-line was processed in a more-or-less uniform way by a single function …

I'm old -- I admit it -- and I feel that command-line applications are still very, very important. Linux, for example, is packed full of almost innumerable command-line applications. In some cases, the Linux GUI tools are specifically just wrappers around the underlying command-line applications.

For many types of high-volume data processing …

See this: "Stop hard-coding business rules" in SD Times. Here's what's exasperating: "Memo to developers: Stop hard-coding business rules into applications. Use business rules engines instead." Business Rules Engines? You mean Python? It appears that they don't mean Python. "Developers can use [a BPM suite or rules engine] and be …
