Even if you create your program in C, it is always possible (for an advanced user/determined competitor) to guess what language (compiler) you're using. And I haven't even mentioned that you can guess Windows Defender is created using Visual Basic Classic (VB6) because one of its windows still use VB6's default icon. There are cues that could hint what language is used to create a program: default icons (e.g. VB6's default icon), interface widgets (notoriously Java's Swing), PEID (which is quite reliable although you could manipulate it), the name (e.g. CPython), included libraries, libraries used (e.g. MSVCRT), etc. And I can't see any obvious advantage you could get by hiding the language you use from your competitors, it isn't like they would switch their language to your language if they can't catch up with you, and they can't anti-advertise you because of the language you used. > I intend to use pyinstaller, so there is no .pyc at all. > The main problem is when I use small programs (as single EXE) sent to > someone as a means of maintenance or debugging. > Sending Python's license file together with one EXE seems to me too > obvious AFAIK (__someone please confirm this__) you don't need to include Python's license in your program, unless you distribute Python's binary/source code (i.e. The Python Interpreter and Friends) in your program. So if you're sending a small program for maintenance or debugging since you don't need to include the Python Interpreter (you assumed that there is already one in the machine) you don't need to include the license. You might need to include the license if the maintenance program is for updating the Python Interpreter though. -- http://mail.python.org/mailman/listinfo/python-list
