10 most useful built-in functions on Python
Among all the programming languages Python is one of the most popular general purpose languages. It is an object oriented programming language with easy to use syntax that making it the perfect language for beginner a pro programmer.
It has a wide range of applications from desktop GUI and mathematical computing to web development. Its interpreter has a number of functions that are always available for use to solve various kinds of problem, which know as built-in functions. In this geek story will find 10 most useful python built-in functions that will help in your daily development process.
It is a string method that concatenates each element of an iterable to the string and returns a string in a flexible way.
It works exactly option of join(). Split() used to break up a string at the specified separator and returns a list of strings.
It used to determine the type of object. If a single argument passed, then it returns the type of the given object. But, when three arguments are passed, then it returns a new type object.
It used to represent a printable string of a given object. This function makes an attempt to return a string that would yield an object with the same value when passed to eval(), otherwise the representation is a string enclosed in angle brackets with the name of the type of the object including the name and address of the object.
When you run a program with a map(), it expects a function to be passed in and return an iterator that applies a function to every item of iterable, yielding the results.
It adds counter to an iterable and return an enumerate object. Iterable must be a sequence, an iterator, or some other object which supports iteration.
The function checks if the object is an instance or subclass of classinfo class and return true if the object argument is an instance of the classinfo argument. If the object is not an object of the given type, the function always returns false.
This built-in function returns a static method for a given function. A static method like class methods that are bound to a class rather than its object.
It is used to apply a particular function that passed as an argument to all of the list elements mentioned in the sequence passed along. It is very useful for performing some computation on a list and returning the result.
As the name suggest, it returns a list of elements of iterable for which function returns true. Iterable may be either a sequence, a container which supports iteration, or an iterator.
