If execution speed is the most important thing, Python would be the 
wrong choice.

If you need to get very close to the hardware (such as when writing an 
operating system), Python would be the wrong choice.

If you are writing software for an environment which has a 
single-language ecosystem (i.e. iOS -> Objective C, or Android -> Java), 
Python would be the wrong choice.

If, for security/business reasons, shipping only the executable, without 
the end user having access to your original source, Python would be the 
wrong language.
