Python #2-Tuples and List In Python

cont......
         Of Python #1- A way to start with Python

what is Tuples ?
 A tuples is sequence of elements .Immutable ordered Sequence.

What is Immutable?
You can not able to change the values once its is declared or Initialized
.
Syntax:
    TupleVariableName = somevalues1, somevalues2,...

Note Worthy : A comma is Tuple create Operator in Python.

Example :
    TuplesVariableName = 1, 2, 3
    print (TuplesVariableName)

Output:
    (1, 2 ,3)

To find the Length of the Tuple?

Syntax:
    len(TuplesVariableName)                   #len is the keyword to find the Length

Example:
   print len(TuplesVarableName)

Output:
    3
_________________________________________________________________________________
*In case if you want to print the particular tuple values

Syntax:
    TupleVariableName [IndexValuesYouNeeded ]

Example:
    TuplesVariableName [2]
Output:
    3

Don't forget to Try it!

What is List?
A list are array like sequences. Mutable  Ordered Sequences.

What is Mutable?
You can  able to change the values once its is declared or Initialized.

Example:
    Lists=['a', 'b', 'c']
    print Lists                             #output will be ['a', 'b', 'c']
    Lists[0]='A'
    print Lists                             #output will be [A'', 'b', 'c']


Syntax:
    ListVariableName = [somevalues1, somevalues2,...]

Note Worthy : Difference between the Tuple and list is ....
-->. In Tuple ( , , ,) is used .where as in List it uses [ , , ,]

Example :
    ListVariableName = [1, 2, 3]
    print (ListVariableName)
Output:
    [1, 2 ,3]

To find the Length of the List?

Syntax:
    len(ListVariableName)               #len is the keyword to find the Length
Example:
   print  len(ListVarableName)
Output:
    3
_________________________________________________________________________________
*In case if you want to print the particular List values

Syntax:
    ListVariableName [IndexValuesYouNeeded ]

Example:
   print  ListVariableName [1]
Output:
    2
