Well im new to python. Ive worked with html, php, and a little C++. For some reason ive having problems saving the file. Im just using the test script hello world. When I go to save the file I save it as hello.py in the default directory and I go to the command line, this is in windows xp pro by the way, and type cd python23 to get to the python directory. I then try to open hello.py I even try python hello.py THe file is no where to be found. Ive also tried python 2.4 and that wont work either. I read a post from august of last year with the same problem and I tried everything verbatum in that post. I believe legacy answered the question. I just get nothing from everything. Do I have to set up something for it to save correctly in windows or did I miss a step. I know this has to be easy but im stumped lol. Any help is greatly appreciated. Even a link to an answer would help. I really want to use python and dont want something this simple to push me away. Thanks again.
