• input()This function is used to read input entered by a user via a standard input device.
• int()This function is used to create an integer from a string, or another number, with an optional base value.
• isinstance() This function is used to check if given object is an instance of specified class.
• issubclass() This function is used to check if given class is an instance of another specified class.
• iter() This function is used to get an iterator object for an iterable.
• len()This function returns the length of an object. The syntax and examples are given in this tutorial.
• list()This function is used to create a list from given iterable.
• locals() This function is used to get the dictionary of local symbol table.
• map()This function takes an iterator and a function, and returns a map with the elements from the iterator and the result of the function applied to each element. The syntax and examples are given in this tutorial.
• max()This function takes two or more elements, or an iterable as argument(s), and returns the element with maximum value. Syntax, and examples are given in this tutorial.
• memoryview() This function is used to get the memoryview of the given bytes-like object.
• min()This function takes two or more elements, or an iterable as argument(s), and returns the element with minimum value. Syntax, and examples are given in this tutorial.
• next() This function returns the next element in an iterator object.
• object() This function is used to create an empty object.
• oct()This function is used to convert an integer to an octal string prefixed with 0o.
• open() This function is used to open a file specified by a path in specific mode.
• ord()This function returns the Unicode point of the given character.
• pow()This function takes base and exponent as arguments, and returns the power: base raised to the exponent. Syntax, and examples are given in this tutorial.
• property() This function is used to create a property with specific setter function, getter function, and delete function for the property.
• range()This function is used to generate a range or sequence of numbers with the defined start, end, and difference between the elements. Syntax, and examples are given in this tutorial.
• repr() This function is used to get the string representation of a given object.
• reversed()This function reverses the order of elements in the given sequence.
• round()This function returns the given number rounded to the specified number of decimal points.
• set()This function is used to create a Set from the items of the given iterable.
• setattr() This function sets a value for an attribute of an object.
