| | My totally uneducated guess is that the Python folks switched to an installer made for Vista. Vista has a whole set of rather childish security traps.  |
| | Which version of PyScripter are you using? I have run into problems with wxPython code with earlier versions of PyScripter. Presently I am using the latest update (version 1.9.1.0). Pyscripter is still in beta mode, but seems to improve with every update. Get the latest update using Tools/Check Updates. Look … |

If need be, you can create this .PIF file using … |
| | Should be a thing of the past. In earlier years of computing, when 16bit operating systems were king, memory used to be addressed in segments/chunks of 64k (2**16). If you crossed one of those segments, you got a fault message. Python's memory manager shouldn't give you any problems like that! … |

| | Do all of us, including yourself, a favor and don't mix tabs and spaces for the 'all important' Python code indentations. Stick with spaces, since tabs depend on the editor settings. Most Python editors can be set to this feature. As for your date entry you could use something like … |
| | Just to let you know that I have been smitten by Ruby thanks to your ruby snippets. I downloaded the whole shmaltz including FxRuby from: [url]http://rubyforge.org/projects/fxruby[/url] I let you know how it works out. I like the syntax and am familiar with it from my Python days. |

 | With `from __future__ import division` I can see a problem in line `for i in range(2,(i2/2)):` you get a float from the division and range does not like floats. Change this line to `for i in range(2,(i2//2)):` Nice thinking here, have to see what Bumsfeld's timing comes up with. |
| | Re: Where's Nemo? Not all modules are modulename.py files. Some of them are .pyc (Python bytecode) or .pyd (Python dll) )files. My best guess is that the module sys is written in C and is part of the Python24.dll/Python25.dll. If you run the Windows version of Python, this file is installed in the … |

| | Python is not for everbody! If you are an entrenched traditional language (C, C++, Java, C#, Pascal) person, Python, because of its elegance, will be too confusing for you.  |
 | Read the first couple of posts in the "Starting Python" thread: [URL]http://www.daniweb.com/techtalkforums/thread20774.html[/URL] IDLE works well, DrPython is better, PyScripter has a few quirks, but is hot!  |
| | Re: Euphoria Ideally you should have an application first and than find the best language to code it in. This in turn means you need to know the basics about a number of languages. I have used C, C++, C#, Delphi/Pascal and Python for some major projects. I keep looking at Ruby. … |

 | Java and Python are much alike, they both compile to virtual machine code (byte code) and then interpret this code to the specific CPU machine code. Java uses pretty much the same ugly syntax that C++ uses, so there isn't much gain there. Daniweb does have a Python forum, look … |
