AST object (mod_ty type) with the public C API. For example, maybe you want to serve content dynamically without loading a new page. And to zip until both iterators are exhausted, you would use itertools.zip_longest. This has led to people who write code which operate on file system paths to assume that such objects are only one of those two types (an int representing a file descriptor does not count as that is not a file path). One crucial feature of Pandas is its ability to write and read Excel, CSV, and many other types of files. pattern-matching statements.
