what is variable?

basically Python variable is a container where you can put your values. an example we are storing to here in a container and the name of that container is X, of course, you can give anything it doesn't matter you can say ABC you can say a box you can give any name. 

so we are storing to here in a container and the name of that container is X

and the value is 2. 

now we have a variable and value. 

how to assign value to the variable:

1st.

x=2

now

x + 67

result: 69

2nd.

x='Bot-'

now 

x+ 'tech'

result: Bot-tech

fetching values:

see the examples:

name= 'youtube'

name=[0]

result: 'y'

name=[1]

result: 'o'

name=[7]

result= 'e'

More examples:

name='youtube'

name=[1:4]

result: 'out'

name=[0:3]

result= 'you'

name=[2:]

result: 'utube'

name=[:2]

result: 'yo'

 changing variable:

name='youtube'

Now I to want to change the variable 'youtube' to 'mytube'.

name='youtube'

'my '+name[3:]

result: my tube
