...in the namespaces where the lambda is defined. In some unusual cases, this change will break code. In all previous version of Python, names were resolved in exactly three namespaces -- the local namespace, the global namespace, and the builtin namespace. According to this old definition, if a function A is defined within a function B, the names bound in B are not visible in A. The new rules make names bound in B visible in A, unless A contains a name binding that hides the binding in B. Secti...
...ing and coding strategies, the mixture of PHP and HTML made deciphering and understanding the code more difficult. Fortunately, Python was designed with documentation in mind, with the use of "doc strings" for modules, classes and methods. Since documentation is actually a part of the language itself, and pydoc is a standard module in the Python distribution, it was easy to extract API documentation to HTML and other formats. Over time, we have found that the syntactic structure of Pyt...

...and give their opinion.) [on incorporation into the Python core] Well it's still our goal and we are working towards that end (we are even beginning to look at converting the documentation to the Python standard). There is a draft manual available. I imagine it may be a year before there is a significant switch- over of the community to start using it (assuming we are succesful in getting them to do so). On the other hand, I don't think that timescale should necessarily be the d...

...ing IDE debugger and the source code analysis engine both contain modules that engage in extremely CPU intensive processing. These modules needed to be written in C in order to squeeze out as much speed as possible. Fortunately, Python is designed to make it quite easy to call back and forth between Python and C or C++. In most cases, we wrote and debugged code first in Python, and then converted by hand into C. This approach worked well for us. Working initially in Python was much more efficien...
