I want to start programming a new program (electronic health care center) in python and before start learning python i wanna make sure that python does have all the features i need to accomplish this project so i wanna ask you does python able to support these features :

1- cross platform (windows + linux)
2- mysql database access
3- 2D graphs (curves)
4- support of international languages
5- can access a scanner and input pictures from it.

and possibly be able to import data from labratory machines (such as CBC machines) to automatically register patient investigations result into the system (not mandatory)

so can python (with any freely available libraries) do all that and still be cross platform ?

thankx in advance

1. Yes, though Python must be installed on Windows (it's included with Linux)
2. Yes. Python can access nearly any database
3. Not directly but you have a wide variety of GUI libraries to choose from, such as Qt, wxPython, or GTK
4. Yes. Python 3 has Unicode support by default
5. Most likely yes, if you know how to write I/O code. I haven't tried it myself but I don't see why it wouldn't work
6. If Python can't do it directly, you can code it in C/C++ and bind it to Python

To answer your overall question, yes, Python should be up to the task you have envisioned. There may be certain things you can't do directly or won't be able to find a library to help with; in those cases, you will probably have to write the necessary code in C and use the Python bindings to link to it.
