Python Built-in Functions

The Python interpreter has some built-in function blocks that are always available for calling in Python programs.

Built-in Functions

abs()to return the absolute value of a number all()to return True if all elements of the iterable are true (or if the iterable is empty). any()to return True if any element of the iterable is true. Return False, if the iterable is empty ascii()to return a string containing a printable representation of an object, but escape the non-ASCII characters in the string returned by repr() using \x, \u, or \U bin()to convert an integer number to a binary string prefixed with "0b" class bool()to return a Boolean value, True or False breakpoint()to drop into the debugger bytearray()to return a new array of bytes bytes()to return a new bytes object callable()to return a True if the object argument appears callable, False if not chr()to return the string of a Unicode code point classmethod()to transform a method into a class method compile()to compile the source into a code or AST object complex()to return a complex number with the value real+imag*1j or convert a string or number to a complex number delattr()to delete the named attribute, provided the object allows it dict()to create a new dictionary dir()to return the list of names in the current local scope, or a list of valid attributes for specified object. divmod()to return a pair of numbers consisting of their quotient and remainder when using integer division by taking two non complex numbers as arguments. enumerate()to return an enumerate object eval()to return the result of the evaluated expression exec()to execute the given Python code filter()to construct an iterator from those elements of iterable for which function returns true float()to return a floating point number constructed from a number or string format()to convert a value to a formatted representation frozenset()to return a new frozenset object getattr()to return the value of the named attribute of object globals()to return a dictionary representing the current global symbol table hasattr()to return True if the object has the specified attribute hash()to return the hash value of the object help()to invoke the built-in help system hex()to convert an integer number to a lowercase hexadecimal string prefixed with "0x" id()to return the identity of an object input()to read a line from input int()to return an integer object isinstance()to return True if the object argument is an instance of the classinfo argument or of a subclass thereof issubclass()to return True if class is a subclass iter()to return an iterator object len()to return the length or the item number of an object list()to return a list object locals()to update and return a dictionary representing the current local symbol table map()to return an iterator that applies functio to every item of iterable, yielding the results max()to return the largest item in an iterable or arguments memoryview()to return a memory view object created from the given argument min()to return the smallest item in an iterable or arguments next()to retrieve the next item from the iterator by calling its __next__() method object()to return a new featureless object. oct()to convert an integer number to an octal string prefixed with "0o" open()to open file and return a corresponding file object ord()to return an integer representing the Unicode code point pow()to return base to the power exp print()to print objects to the text stream file property()to return a property attribute range()to return a range repr()to return a string containing a printable representation of an object reversed()to return a reverse iterator round()to return number rounded to ndigits precision after the decimal point set()to return a new set object setattr()to assign the value to the attribute, provided the object allows it slice()to return a slice object representing the set of indices specified by range sorted()to return a new sorted list from the items in iterable staticmethod()to transform a method into a static method str()to return a str version of object sum()to return the total of iterable from left to right super()to return a proxy object that delegates method calls to a parent or sibling class of type. tuple()to return a tuple type()to return the type of an object vars()to return the __dict__ attribute for a module, class, instance, or any othe object with a __dict__ attribute zip()to return an iterator of tuples, where the i-th tuple contains the i-th element from each of the argument sequence or iterables. __import__()to import the module name, potentially using the given globals and locals to determine how to interpret the name in a package context
