PyInstaller. Instant Python. This is a minimal crash-course in the programming language Python. To learn more, take a look at the documentation at the Python web site, www.python.org; especially the tutorial. If you wonder why you should be interested, check out the comparison page where Python is compared to other languages. This introduction has been translated into several languages, among them Portuguese, Italian, Spanish, Russian, French, Lithuanian, Japanese, German and Greek, and is currently being translated into Norwegian, Polish, and Korean. Since this document still might undergo changes, these translations may not always be up to date. Note: To get the examples working properly, write the programs in a text file and then run that with the interpreter; do not try to run them directly in the interactive interpreter - not all of them will work.
