Learn PYTHON for DevOps ♾️in 3 DAYs.

Prerequisite: PYTHON INSTALLATION WITH VIRTUAL ENVIRONMENTS

install the python latest version
so visit python.org

What is VS code?
it's an editor where you can read and write code, simple :). it's good to download VS code and install it.

How to install it ?
open terminal in VScode and create folder for project
and create virtual environment

pip install virtualenv

virtualenv -p python3.10 <name>

it will create the env folder in your directory or folder
now active this environment

source env/bin/activate

python --version

deactivate

Day-1 : YOUR FIRST CODE

Then you say that, ** i'm not a programer or coder?** it's mean you are unable to transfer your need file <code>.py to the OS compiler to compile and operate your task as you wish/need.

open the interactive terminal of python

python

Variable and constance
V >> a=20
C >> 20

data type in puthon
[int,float,str,bool]
int >> a=20
float >> a=20.01
str >> a="asad"
bool >> coding=true


type(a) && type(coding)

output:

<class 'int'> <class 'bool'>

take input from user
`

num=input("Enter your number")

**take input from user with type casting**

num=int(input("enter your number"))
`

CODE BLOCK #1

let make a script of python using simple conditional statement.
my_first_code.py

env=input("enter your cloud: ")
if env == "aws" or env =="AWS":
print("you are in AWS environment")
else:
print("you are in an other cloud environment")

you can run this file from VScode terminal or OS terminal by just define the file name with python command.remember : terminal open in the same working path

python *my_first_code*.py

or

python3.10 *my_first_code*.py

let make another calculater script of python using simple conditional statement.
calculater_code.py

num1 = float(input("enter your first number")
num2 = float(input("enter your second number")
opr = input("enter your operator")

if opr == "+":
output=num1+num2
if opr == "-":
output=num1-num2
if opr == "*":
output=num1*num2
if opr == "/":
output=num1/num2
if opr == "%":
output=num1%num2
print("you calculation is equal to ",output)


if num1 < 3:
print("you are in an other cloud environment")


CODE BLOCK #2

let make another script of python using list Function.
my_Second_code.py

names = list([ "syed","johan","nihao","Ramesh"])
//// to get the full list of names.
print(names)
//// to get the list of names by calling them separately.
print(names[0])
print(names[1])
print(names[2])
print(names[3])


READ BLOCK #1

let start reading the most basic and advance concept of Python by just go-throw the linkedin Skill Quiz assessment.

the best thing of this link is an Open-source python repository, So the new changing are Committed and new question is added by the multiple people which is almost an python expert.
