Python builtins Module
Example
Use a few common built-in functions:
# Names: Emil, Tobias, Linus
print(len(["Emil", "Tobias"]))
print(sum([1, 2, 3]))

Definition and Usage
The builtins module provides direct access to all built-in identifiers of Python.
Use it to reference built-in functions, exceptions, and constants explicitly, or to inspect/override built-ins.
Members

| exec() | Execute Python code dynamically. |
| filter() | Construct an iterator from elements of iterable for which function returns true. |
| float() | Construct a floating point number. |
| format() | Return a formatted string using the given format spec. |
| frozenset() | Create an immutable set. |
| getattr() | Return the value of the named attribute of an object; fallback if missing. |
| globals() | Return a dict of the current global symbol table. |
| hasattr() | Return True if an object has the named attribute. |

| help() | Invoke the built-in help system. |
| hex() | Convert an integer to a hexadecimal string prefixed with 0x. |
| id() | Return the identity (memory address) of an object. |
| input() | Read a line from input, returning it as a string. |
| int() | Construct an integer number. |
| isinstance() | Return True if an object is an instance of a class or tuple of classes. |
| issubclass() | Return True if a class is a subclass of another class or tuple of classes. |
| iter() | Return an iterator from an object. |
| len() | Return the number of items in a container. |
| list() | Create a new list. |
| map() | Return an iterator that applies function to every item of iterable. |
| max() | Return the largest item in an iterable or the largest of two or more arguments. |
| memoryview() | Create a memory view object of the given bytes-like object. |
| min() | Return the smallest item in an iterable or the smallest of two or more arguments. |
| next() | Retrieve the next item from an iterator; default if exhausted. |
| oct() | Convert an integer to an octal string prefixed with 0o. |
| open() | Open file and return a corresponding file object. |
| ord() | Return the Unicode code point of a one-character string. |
| pow() | Return base raised to power; with three args, compute modular exponentiation. |
| print() | Print objects to text stream file. |
| property() | Return a property attribute; used as a decorator to define managed attributes (with optional getter/setter/deleter). |
| range() | Return an immutable sequence of numbers. |
| repr() | Return a string with a printable representation of an object. |
| reversed() | Return a reverse iterator over a sequence. |
| round() | Round a number to a given precision in decimal digits. |
| set() | Create a new set object. |
| slice() | Create a slice object to specify how to slice a sequence. |
| sorted() | Return a new sorted list from the items in iterable. |
| staticmethod() | Return a static method; used as a decorator to define methods that do not receive an implicit first argument. |
| str() | Return a string version of object. |
| sum() | Sum items of an iterable. |
| super() | Return a proxy object that delegates method calls to a parent or sibling class. |
| tuple() | Create a new tuple. |
| type() | Return the type of an object; can also create new types. |
| vars() | Return the __dict__ attribute for a module, class, instance, or the current locals. |
| zip() | Return an iterator of tuples, where the i-th tuple contains the i-th element from each of the argument iterables. |
