python *variable code example

Example 1: what is a variable?

-- In programing variables exist in 99%(if not all) of programing languages:
-- Think of them as little boxes that can store data
-- some examples:

-- C#
  count = 0;
  While true
  {
    count = count + 1;
    print(count);
  }
  
-- Python
	count = 0
	While True:
    	count = count + 1
        print(count)
        
-- as you see, both of these programs will output:
1
2
3
4
5
6
7
8
9
...
-- and it will keep counting till you crash the program.

-- (ps I am using sql cause it looks nice and hilights a bunch of stuff)

Example 2: variables

1-GLOBAL variables allow you to access data
between collections, requests, test scripts,
and environments. Global variables are
available throughout a workspace.

2-COLLECTION Only accessible within the same collection and
can not be accessed anywhere else
COLLECTION variables are available throughout 
the requests in a collection and are independent
of environments, so do not change based on the selected environment.
I use collection variables when
I use single environment like url details.
We can refer to the variable by using {{}}(double curly brace)
and  it can be used anywhere

3-ENVIRONMENT Variable , a variable that accessible
only when the environment is active 

Usually used for an app with multiple environment ,
we can use env variable to store variable with same name
and different value to store environment specific data 

for example : 

xxxNamed app has 3 environments with different
URL and Crendentials 

But all endpoints are exactly the same no matter what
environment you work on 

so we can create 3 environment called 
QA1 , QA2 , QA3 and run same set of request 
by selecting different environment.

Only one environment can be active at a time.


4-LOCAL variables are temporary, and only
accessible in your request scripts. 
Local variable values are scoped to a 
single request or collection run, and are no longer
available when the run is complete.


5-DATA variables come from external CSV and JSON files
to define data sets you can use when running collections
via the Collection Runner.

Example 3: Variable

<?php

$txt = "Hello world!";

$x = 5;
$y = 10.5;

?>

Example 4: Variable

yes = 5
print(yes)

Example 5: variable

//If you dont want to indicate anything yet//
int *Name of variable*;
//If you want to indicate something to use later on//
int *Name of variable* = *number or string*;
