Almost everything points positively for Python. Thanks to all of you who have responded. But please also tell me the disadvantages of Python. If I start using Python, I should be aware of the price I am paying. Speed is not a big problem for me, so an interpreted language is fine. Is packaging/installing very messy? Do I create dozens of files for a simple program calculating the sum of two numbers and product of two numbers in text boxes with one command to be clicked? Can I learn this much in the first couple of hours?

I have learnt enough VB.net to manage most of the things I will need, but it always gives me a feeling that it is not meant for the kind of things I am doing. And you never know when Microsoft will kick us out of VB.net also. For the sake of keeping software compatible with new versions of Windows, you need to keep changing things in the software, which takes too much time. You might ask if it is really necessary to move from VB6 to VB.net because Microsoft will still not be able to kill VB6 very soon, thanks to VBA used in Excel. If my reasoning is wrong, please correct me. I am just an engineer, not a good programmer.

However, because it is an Interpreted language, the step to a bundled, self-contained image is platform dependent. There python compliers (as opposed to interpreters) for some, but not all platforms, and there is a very active JiT compiler project that would fall somewhere in between.
