Which is faster Python or C++?
While Python may be less efficient than C/C++ at runtime, during development it’s much more efficient. Interpreters read each line of code, parse it, do runtime checks and call routines in order to execute the operations in the code. This can lead to slower runtime speeds and higher energy consumption with Python.
Which is better C or Python?
Ease of development: – python has very fewer keywords and more free English language syntax whereas C is far more difficult to write and maintain. Hence if you want easy development process go for python. Performance: – Python is much slower than C as python takes significant CPU time for interpretation.
Which is faster C or C++?

How do we program bios of computer?
BIOS (basic input/output system) is the program a personal computer’s microprocessor uses to get the computer system started after you turn it on. It also manages data flow between the computer’s operating system and attached devices such as the hard disk, video adapter, keyboard, mouse and printer.
