Recognizing speech (speech-to-text) with the Python speech module (Python)

2015-10-22T13:09:02-07:00

Python recipe 579115 by Vasudev Ram (language_translation, python, python2, speech_recognition, windows).

This recipe shows how to use the 'speech' (or 'pyspeech' - it seems to have two names) Python library to make the computer recognize what you say and convert it to text. Note: This library did not always give correct results for me, so it may not be advisable to use it in production. Also, the pyspeech site says that the library is no longer being maintained. Use at your own risk.

Python recipe 578226 by Jonathan Frere (function, instance, isinstance). Revision 2.

So it turned out that I needed a way of ensuring that all members of an iterable are instances of a certain class. Here, therefore, is the isallinstance() function.

METACLASS AND DEEPCOPY (Python)

2012-02-26T15:43:01-08:00

Python recipe 578053 by thonpy (deepcopy, equal, list, metaclass, sign).

I would like to solve this excercise: Traditionally object-oriented programming provides two different modes for cloning an instance or a structured data type: shallow and deep copy. The former has the effect to clone exclusively the external shell and not its content originating a quite fastidious aliasing effect. The latter, instead, copies the shell and its content recursively creating two completely separate copies of the instance.

As you know, Python's programs suffer of the aliasing effect when you copy an instance of a class or a structured type (e.g., a list) with the = operator. As showed in the following example:

l=[0,1,2] mylist=l mylist[2] = ’B’ mylist [1, 2, ’B’] l [1, 2, ’B’

The exercise consists of defining a meta-class which implements the deep copy on the assignment operator and binding this to the standard class list. Such that the following behavior can be yielded

State FIPS Codes Dict (Python)

Make a Class Available in its Own Definition Body! (Python)

2011-09-15T05:36:36-07:00

Python recipe 577867 by Eric Snow (class, metaclass).

This may sound too good to be true, but see for yourself. No time machines involved. Just plug in this metaclass and look for __newclass__ in your class body. It's not perfect, but the problematic corner cases are more bark than bite.

dealing with directory paths with ~ (Python)

2010-06-16T23:17:20-07:00

Python recipe 577270 by roopeshv (directory, expanding, paths). Revision 2.

Dealing with directory paths which start with ~ which are passed as paramaters, to os module functions.

Here is what I think python doesn't do for me:

>>> import os
# suppose my home = curdir = /home/rv
>>> os.path.abspath('.') 
'/home/rv'

Now if I want to go to folder /home/rv/test if there is no folder by name /home/rv/~/test/

# This is what happens by default.
>>> os.path.abspath('~/test')
'/home/rv/~/test'

>>> os.chdir('/home/rv/some/dir')
# doesn't matter if the resulting path exists or not.
>>> os.path.abspath('~/test')
'home/rv/some/dir/~/test'

This would be more sensible I guess:

# if /home/rv/~/test doesn't exist
>>> os.path.abspath('~/test')
'/home/rv/test'
