Types of data in PYTHON

Data Types


  • Sets : 

A Set is an unordered collection data type that is iterable, mutable and has no duplicate elements. Python’s set class represents the mathematical notion of a set. The major advantage of using a set, as opposed to a list, is that it has a highly optimized method for checking whether a specific element is contained in the set. This is based on a data structure known as a hash table.

The Syntax of the set is : 
Define: a={Elements of set}

Example: a={1,2,3,4}
      print(a)


Warning: Please, always maintain the Indentation, as Python is too much sensitive about the Indentation(maintain the braces in the program Step by Step) Otherwise it will Throw an Error: "Indentation Error".

  • Tupples :  

A Tuple is a collection of Python objects separated by commas. In some ways, a tuple is similar to a list in terms of indexing, nested objects, and repetition but a tuple is immutable, unlike lists which are mutable.

The Syntax of the Tupple is :
Define: a=(Elements of tupple)

Example: a=(1,2,3,4)
      print(a)


  • Booleans : 
Boolean values are the two constant objects False and True. They are used to represent truth values (although other values can also be considered false or true). 
                                                     Example: a=True
      print(a)

     a=False
      print(a)


  • Lists : 
Lists are one of the most powerful tools in Python. They are just like the arrays declared in other languages. But the most powerful thing is that list need not be always homogeneous. A single list can contain strings, integers, as well as objects. Lists can also be used for implementing stacks and queues. Lists are mutable, i.e., they can be altered once declared.

The Syntax of the List is : 
Define: a=[Elements of list]

Example: a=[1,2,3,4,5]
    print(a)


  • Dictionary : 
In python, a dictionary is similar to hash or maps in other languages. It consists of key-value pairs. The value can be accessed by a unique key in the dictionary.

The Syntax of the Dictionary is : 

Define: a={Keys of Element:Elements of Dictionary}

Example: a={1:2,3:4,5:6,7:8}
                 print(a[1],a[3],a[5],a[7])
   #Above will Print the Elements 
print(a)
           #Above will Print the Entire Dictionary


  • Type Keyword :

Python has a built-in method called a type which generally comes in handy while figuring out the type of variable used in the program in the runtime.
The Syntax of the Type Keyword : 
Define: type(Object)

Example: a={1:2,3:4,5:6,7:8}
    print(Type(a))
#Output : "Dict"

Write Your First Python Program

Let's keep it Simple, Start Writing Your First Program : Open Your Pycharm and open a new file as python 3, it will look like : If you are using it the first time, you may get the error Interpreter path is not Defined  Now, let us give it a solution, In "Pycharm" go to the setting or use (Ctrl+Alt+s) key to open the settings. Then, go to the project and set the path of the python interpreter Close the setting after applying the setting. Okay, now you are done let us start writing your first program. Just open a new file as "Python 3", it will look like this :  Give it a name as My first program. Let us start by printing "Hello World !!", as it is the most basic thing you can start with any language. Its simple, just write the code:                                                    print("Hello World !! ")   and run the ...

Introduction to Python

 It is an interpreted high-level programming language for general purpose programming. Python features a dynamic type system and automatic memory management. It supports multiple programming paradigms including object-oriented programming, imperative, functional and procedural and has a large and comprehensive standard library. like Django, beautiful soup etc. So the main question arises why python when there are several other languages to learn and work on? Why python? Python is simply a much cooler language. It is very easy to code. Anyone can learn python syntax within a day. It's easy to read. Being a high-level language one can easily understand the code simply by reading it.  Being an Open source language one can download it not only for free, but its source code is available to public this, means you can edit it, change, it use it and distribute it too. There are various modules according to user needs. That is it exhibits a huge amount o...

Basics of Python Let's start with the usage of 'print' function, the syntax of the 'print' function is : print("Text under this will be Displayed ") the basic definition of print is : print(value, ..., sep=' ', end='\\n', file=sys.stdout, flush=False)\n\nPrints the values to a stream, or to sys.stdout by default.\nOptional keyword arguments:\nfile: a file-like object (stream); defaults to the current sys.stdout.\nsep:string inserted between values, default a space.\nend:string appended after the last value, default a newline.\nflush: whether to forcibly flush the stream. The above definition of print you can get by entering docstring and flexibility of python print function ,syntax to get info of any function that used in the python is by using the docstring, we can get to know about the parameter that can used or should be passed through a pre-defined function. The syntax for "Docstring" keyword is : print...
