WebCython(/ˈsaɪθɒn/) is a programming language, a (non-strict, at least for Python 3) supersetof the Python programming language(with slightly different semantics), designed to give C-like performance with code that is written mostly in Python with optional additional C-inspired syntax. [5][6] WebCython is a hybrid programming language used to write C extensions for Python language. Combining the practicality of Python and speed and ease of the C language it’s an exciting language worth learning if you want to build fast applications with ease.

WebMar 26, 2024 · That’s right. Heh, so NaN is, pretty literally, “not a number”, but infinity is ? Math-wise at least that doesn’t make sense, infinity has a meaning as a notation in the context of limits, but it’s neither a number nor even a value.
