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++?
