    ...lists than the previous implementation, and reported to be just as fast on randomly ordered lists on several major platforms. This sort is also stable (if A==B and A precedes B in the list at the start, A precedes B after the sort too), although the language definition does not guarantee stability. A potential drawback is that list.sort() may require temp space of len(list)*2 bytes (*4 on a 64-bit machine). It's therefore possible for list.sort() to raise MemoryError now, even if a comparison...

  • Python Success Stories

    ...lists of properties that define each unique custom ERP implementation. This has reduced maintenance costs by an order of magnitude: The typical ERP5 system contains 100,000 lines of code, rather than the 1,000,000 lines of code required in similar projects based on traditional programming techniques. Python supports efficient metaprogramming through powerful introspection features that allow programs to inspect and modify code at runtime. Java's introspection are by contrast quite poor and infle...

  • Comparing Python to Other Languages

    Comparing Python to Other Languages Comparing Python to Other Languages Disclaimer: This essay was written sometime in 1997. It shows its age. It is retained here merely as a historical artifact. --Guido van Rossum Python is often compared to other interpreted languages such as Java, JavaScript, Perl, Tcl, or Smalltalk. Comparisons to C++, Common Lisp and Scheme can also be enlightening. In this section I will briefly compare Python to each of these languages. These comparison...

    Bugs in Python 2.3.2 <h3>Bugs in Python 2.3.2</h3> <ul> <li>IDLE now executes code in a separate process. To communicate between the main process and executing processes, IDLE opens a socket to 127.0.0.1 (the local machine). Some firewalls running on Windows machines interfere with this and can cause either silent failures or erroneous popup windows from the firewall. This problem only occurs if you run a firewall on the same machine as IDLE.</li> </ul> &...
