As an interpreted language, Python has a slow speed of execution. It is slower than C and C++ because it works with an interpreter, not the compiler.

The language is seen as less suitable for mobile development and game development. It is often used on desktop and server, but there are only several mobile applications that were developed with Python. Another disadvantage Python has is the runtime error. The language has a lot of design limits and needs more testing time. The programmer has the possibility to see bugs only during run time.
