• Comparing Python to Other Languages

  ...declarations for a and b, and does not allow overloading of the + operator for instances of user-defined classes. For these reasons, Python is much better suited as a "glue" language, while Java is better characterized as a low-level implementation language. In fact, the two together make an excellent combination. Components can be developed in Java and combined to form applications in Python; Python can also be used to prototype components until their design can be "hardened" in a Java...

• What's new in Python 1.5 and beyond

  ...namespace instead of as a submodule. For more information, see Built-in Package Support. The new "re" module (Perl style regular expressions) is here. It is based on Philip Hazel's pcre code; the Python interfaces were put together by Andrew Kuchling. The regex module is declared obsolete. In support of the re module, a new form of string literals is introduced, "raw strings": e.g. r"n" is equal to "\n". All standard exceptions and most exceptions defin...

• Built-in Package Support in Python 1.5

  Built-in Package Support in Python 1.5 Built-in Package Support in Python 1.5 Starting with Python version 1.5a4, package support is built into the Python interpreter. This implements a slightly simplified and modified version of the package import semantics pioneered by the "ni" module. "Package import" is a method to structure Python's module namespace by using "dotted module names". For example, the module name A.B designates a submodule named B in a package named A. Just like...

• Notes

  ...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. Section 4.1 ...

• What's New In Python 3.0

  ...namespace. The long-deprecated argument "pend" of PyFloat_FromString() has been removed. The dir() function has been extended to call the __dir__() method on its argument, if it exists. If not, it will work like before. This allows customizing the output of dir() in the presence of a __getattr__(). Removed support for __members__ and __methods__. Removed indexing/slicing on BaseException. input() became raw_input(): the name input() now implements the functionality formerly known ...
