WebCython extends the Python language with explicit type declarations so that it can generate efficient C extensions through compilation. The main way to declare data types in Cython is through cdef statements. The cdef keyword can be used in multiple contexts, such as variables, functions, and extension types (statically-typed classes). Variables WebAt a glance. Each chart bar shows, for one unidentified benchmark, how much the fastest Cython program used compared to the fastest Python 3 program. (Memory use is only compared for tasks that require memory to be allocated .) These are not the only compilers and interpreters. These are not the only programs that could be written.
