dir()

dir() is a Python function in the Built-in Functions category. Returns a sorted list of names in the current scope or of an object's attributes. The syntax is dir(object=None). Parameters: object — optional object to inspect. Returns: List of attribute names. A typical example: dir([]) # ["__add__", "__class__", ..., "append", "count"]. A close sibling is print(), which prints objects to the text stream, separated by `sep` and followed by `end`. A close sibling is len(), which returns the length (number of items) of an object. Works with sequences, collections, and strings. A close sibling is range(), which returns an immutable sequence of numbers. Commonly used in for loops. A close sibling is type(), which returns the type of an object, or creates a new type with three arguments.
