Python variable

 



Hi...

Let's go through some factors about Python Variables in this blog


1. What variables are?

2. Create our first variables in Python 

3. Learn about variable " type() " 

So let's get started

Well to understand easily we can consider Variable as a box where we can store data. Data can be of any type such as text, images, video, audios, etc.


Now, the variable contains two things :
1. Name
2. Value


A) Assign " Integer type " value in the variable name Number.
here "Number" is the variable name and the value assigned in it is "10" 👇.









Whenever we type the Number, it will show the contained value here "10"☝.


B). Now, We can assign " String type " data on the same variable
Number = "JK"




C). Now, We can assign "Float type " data on the same variable






let's check the type of value stored in our variable "Number"

How??

Yea!... you got it right it's now time to use  " type( ) " keyword :👇👇




Important Points :

#1. Python variables are case sensitive means variable name "Number" is different from "number".

#2. Python variables are Dynamically typed variable means there is no need to define a variable type like int, float, char, etc before assigning value. But in another languages like C, C++, Java, etc we need to define data type before assigning any value in the variables.  C, C++, Java are the statically typed() whereas python is Dynamically typed.

#3. The last value stored is retained in the variable.


Review :

1. Variables are like boxes that store data.

2. Variables can be defined as -     variable = value

3. In Python, Variable type can be changed Dynamically.

4. Use the type() variable to get variable type.


Great, enjoy practising till next blog comes☺...
