Variables

In Python, variables are defined with certain rules. 




Let's get started reading about them!! 

  • Don't create variable with a number
    • Eg: '12a'; #is wrong.
  • Don't define any variables with space, instead we can define with intend mark.
    • Eg: new word = Hello ; #is wrong
    • new_word = Hello ; #is correct

  • Don't create any variable contain any of these symbols:

    :'",<>/?|\!@#%^&*~-+

  • it's considered best practice (PEP8) that names are lowercase with underscores

  • avoid using Python built-in keywords
    • built-in keywords like list and str
  • avoid using the single characters l (lowercase letter el), O (uppercase letter oh) and I (uppercase letter eye) as they can be confused with 1 and 0

Numbers

In this blog, we will learn about numbers in Python and how to use them. Types of Numbers: Python has various "types" of numbers (numeric literals). We'll mainly focus on integers and floating point numbers . Integers are just whole numbers, positive or negative. For example: 2 and -2 are examples of integers. Floating point numbers in Python are notable because they have a decimal point in them, or use an exponential (e) to define the number. For example 2.0 and -2.1 are examples of floating point numbers. 4E2 (4 times 10 to the power of 2) is also an example of a floating point number in Python. we can do basic arithmetic function in python . See the below examples. # Addition  2+1 o/p - 3 # Subtraction  2-1 o/p - 1 # Multiplication  2*2 o/p - 4 # Division  3/2 o/p - 1.5 Note: Python 2 treats numbers that you type without any digits after the decimal point as integers, which can lead to some unexpected results during division. For example, if you ...

SPLUNK

                                                       I have came across 'Splunk' in google, where I got the below collective informations, which may help for you.  Some saying in a definition format as it is used for monitoring, searching, analysing and visualising the machine-generated data in real time.  Some saying this as "Google for logs" .  So, SPLUNK is a software platform  to search, analyse and visualise the machine-generated data, which is none other than the log file which is gathered from the websites, applications, sensors, devices etc. . Why we go for SPLUNK: Generally machine data are complex to understand, in an unstructured format and ot suitable for making analysis / visualisation!!! Splunk allows you to accept any data formats like .csv, json, log formats etc. Splunk performs capturing, in...
