Declaring a string is simple, see the Standard “duck types”¶ In typical Python code, many functions that can take a list or a dict as an argument only need their argument to be somehow “list-like” or “dict-like”. A specific meaning of “list-like” or “dict-like” (or something-else-like) is called a “duck type”, and several duck types that are common in Types¶. Cython uses the normal C syntax for C types, including pointers. It provides all the standard C types, namely char, short, int, long, long long as well as their unsigned versions, e.g. unsigned int.The special bint type is used for C boolean values (int with 0/non-0 values for False/True) and Py_ssize_t for (signed) sizes of Python containers.

When using the C++ interface for Python types, or calling Python functions, objects of type object are returned. It is possible to invoke implicit conversions to subclasses like dict. The same holds for the proxy objects returned by operator[] or obj.attr(). Go to your Start menu (lower left Windows icon), type "Microsoft Store", select the link to open the store. Once the store is open, select Search from the upper-right menu and enter "Python". Open "Python 3.7" from the results under Apps.
