requires_python
The requires_python attribute is optional. This attribute allows the extension to specify the versions of Python it can work with. The syntax and semantics are a subset of PEP 440 version specifiers. Its value consists of one or more version specifier clauses delimited by commas. A specifier clause consists of a comparison operator and a version number. if not specified, a default value of >=2.7 will be used. Valid comparison operators are as follows:
