How to use Cython Programming Language
Cython is aimed at being the superset of the Python programming language. It is so designed that it gives C like performance along with codes mostly written in the Python language allowing extra syntax that is inspired by C. When Cython is compiled it gives CPython extension modules. It provides lesser computational overhead than Python at run-time. C and C++ codes can be wrapped into the Cython modules. The Cython is dependent on the Python interpreter and standard library. Cython employs optimistic optimizations, optional type inference, low control structures overheads, and low function call overhead. Its performance is dependent on the generation and implementation of the C codes. The Cython programming Language is much like Python with very little difference. To understand this, let us take, for example, Python code and its relevant Cython code.
Python code:
Python3
def f(x): return x * * 2 - x def integrate_f(a, b, N): s = 0 dx = (b - a) / N for i in range (N): s + = f(a + i * dx) return s * dx |
Cython code:
Python3
cdef double f(double x): return x * * 2 - x def integrate_f(double a, double b, int N): cdef int i cdef double s, x, dx s = 0 dx = (b - a) / N for i in range (N): s + = f(a + i * dx) return s * dx |
In the two codes, it can be seen that very little has been changed. Only the variables have been explicitly declared and it affects the performance thereby improving its speed.
Facts about Cython Programming Language
Cython is a programming language. It can run on Windows, macOS, and Linux operating systems. It had a version ranging from 2.6 to 3.8. Cython 3.0.0 is under development. In Cython, the Code written in Python is converted to C language. High traffic websites such as Quora use Cython Programming language.
