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

BIG DATA ANALYTICS

BIG DATA ANALYTICS Have you ever hit upon how Amazon and Flip kart could possible verdict what we want; how the Google auto completes our search; how the YouTube looks into videos we want to watch? When we open YouTube, we will be at sixes and sevens, when we find ads related to what we have searched earlier in the past days. This is where we find ourselves in the era of big data analytics. More than 3 trillion bytes of information are being generated everyday through our smart phones, tablets, GPS devices, etc.  Have we thought about what can be done with all these information? This is where the data analytics comes into play. Big data analytics is just the study of future build up to store data in order to extract the behaviour patterns. The entire social networking website gathers our data which are related to our interest which is usually done by using our past search or any other social information. Data analytics will lead to a walkover in near future....

CLOUD COMPUTING SERVICES

Services provided by Cloud Computing   1. Software as a service :  It is process by which the software will be provided by the cloud server's. Instead of using the software in our local machine we can directly use the cloud services directly to get our work done.   Example : Google Slides, Google Docs, Google Sheets, Zoho Writer,....etc. 2. Platform as a service : It is process by which you can directly use platform like windows , linux , Mac, ....Which ever you need to done your work. Example : There are certain software which might be run only certain platform. Assume I have windows operating system but i am doing research in BIG DATA. There Linux Operation system might be handy for my research work. Where it is hard for me to put Operating System again and again to my local machine and taking backup data. So Cloud Computing Services Makes our work easier whatever platform we need it will provide u...

Python #23-Regex findall() and sub() in Python

Previous Post   :                            Python #22-Regex match() and search() in Python Next Post         :                            Coming soon........ re.findall(): It find all sub strings where the RE matches, and return them as a list. This function is used to catch all the matching patterns in the strings. Note Worthy: re.match() + re.search() = re.findall() Syntax:   re.findall(pattern, string) Source Code:   import re   variable = re.findall(r"Google", "Google Bird learn around Google and gives the best contents to the viewrs")   print variable Output:    ['Google', 'Google'] re.sub(): This is used to search a pattern in the string an replace with the new sub string. Syntax: re.sub(pattern, replac...
