What Is The Usage Of Help() And Dir() Function In Python?

Python Functions(i2tutorials.com)

Python is becoming the imperative language to learn because of its prosperous ecosystem. It can be used for web development, scientific computing, and artificial intelligence, almost for everything. The user-friendly syntax makes this language easier and allows programmers to convey their idea in fewer lines as compared to the other programming languages. This multi-paradigm language is supportive of big organizations.  Keen learning of python language contains many aspects including its libraries, tools, objects, functions, and others. The usage of all these elements makes this language much fruitful and functional than other ones.

To perform the particular action in python, functions are used as a block of reused code that brings additional flexibility to the language. Functions are equally crucial as other objects in python, which helps to rescue the code, improve the clarity and for information protection. Help() and dir(), are the two functions that are reachable from the python interpreter. Both functions are utilized for observing the combine dump of build-in-function. These created functions in python are truly helpful for the efficient observation of the built-in system. For the deep study of these two functions just analyze the explained information that is given below.

 Utilization OF Dir() Function In Python

 There are two key functions of python built-in function and users define a function. Dir() is the powerful inbuilt function in python that returns a list of valid methods and ascribe of any objects including modules, lists, strings, and others. It does not behave similarly with each object. It also doesn’t focus on complete information but surely aims to assemble the most applicable one.

 Dir() Syntax:

 dir({ object})

Dir() Parameter:

 Object [optional]: Takes object name

Benefits OF Dir() Function In Python

 Dir() function can work even in large projects

Proves truly helpful while working with various classes’ functions differently

Lists out all the obtainable attributes for module, lists, and dictionaries

Greatly assists to know about the new modules quickly

 Utilization Of Python Help() Function

 The name of the help function evidently describes its usage in python. It is also called built-in python help system. This method works for the correlative use. This function returns the assistance that linked to the python module, object, and method but if it called with the approachable argument. On the other hand, without argument, it will return the help associated with presently running program module. When you initiate recent python interpret, just write help() and press the enter button. It will quickly present the python help() usefulness. Users just have to enter the name of any keyword, topic or module to attain the help on writing python program and to quit or return to the interpreter, just type quit.

 Help() Syntax:


Help() Parameters:

The help() function grab maximal parameters

Object is optional

Benefits Of Help() Function In Python

It is an easy-to-use function

It allows reduce the complexity of the code

It also assists to solve arduous problems in a simpler way
