Web application using python with Google maps API

        => In this blog we are going to develop a web app using Html, CSS and Javascript for Front end and back end using Python. Let us have a high level view of the web app, it is divided into four modules :-

1] input.html (we get input from user )

2] master.py (We get user input from input.html and pass it compute.py)

3] compute.py (Perform desired operations on user input and pass back the result to master.py)

4] output.html(Get the result from master.py and display it for user)

Source Code:-

1.  input.html
2.  master.py
3.  compute.py
4.  output.html

Working of Web app:- 

•                  User enter the input through input.html and it is passed to master.py using flask then master.py sends the user input to compute.py, after performing calculations on user input, compute.py send the results back to master.py,

•               Finally master.py sends the result to output.html to display the result using Flask. output.html displays the output and wait till the user press Reset button, once Reset button is clicked then it redirects to input.html and this cycle goes on. 

•           The module master.py assign the task to each module and acts as a bridge of communication between all the modules, here we implement Flask(Micro web framework for python).

                                                            WORKING CYCLE

INPUT VIEW

OUTPUT VIEW

Description:-

         We are getting two costs as input and passing it to the Gurobi optimizer for solving facility location problem, it is done in compute.py, It gives us the locations and they are displayed in the output.html. It displays the new locations with green markers and lines are drawn between the new markers and the old markers(red). Using two costs entered by user, a pie chart is drawn just to give a demo of pie chart. Click on the markers to get information regarding it. Hit the Reset button to get back.

Useful points:- 

• In this application as we are display places in google maps we need to use google maps API. To use it we require  Google maps API key get it from the Google-API-KEY
• If you are using Pycharm IDE for developing python web app, create a new project, right click on project => create a sub folder with name 'templates', right click on templates => create 2 html files one for input and another for output. In the same project create 2 python files one for master and another for compute.
• To solve facility location problem we are using Gurobi optimizer download it from gurobi-optimizer. Got the source code for Gurobi from   http://examples.gurobi.com/facility-location/#demo

Updated Snake Game

                                 UPDATED SNAKE GAME

Description

This game provides all of the challenge expected from an "impossible" game while also making it's code very simple.

what's New

Update 1.01
Bug fixes and tweaks.

FLAW'S AND RECTIFICATION
There are 2  major Flaws in before game:-
1] speed of snake does not increases as score increases.
2] Even though Snake's Head touches it's Tail, game is allowing us to play further instead of                   showing GAME OVER CARD.

In this Update I fixed those 2 Flaws:-
=>First one is fixed by decreasing the TIME DELAY as Score increases.
=>Second is resolved by logical analysis that is if first circle touches any other circle then it comes         out of loop.

                                                                               .............HAPPY CODING,
                                                                                                  VISWADEEP.

Snake Game

                                    SNAKE GAME

Idea behind this Game:

1] To confine the snake draw a border in such a way that if it crosses the border then          player should loose.    

2] Create a small snake with some filled ovals of same radius  (r) side by side this can     be  achieved by placing circles with a spacing of 2r .

3] Movement of snake can be set by assigning the arrow keys to it.

4] Food can be created at random places by using Random class.

5] Each time the snake catches the food not only score but also length of the snake         has   to be increased.

6] Speed of the snake can be varied by using Thread.Sleep() function.

7] Concept of double buffering is used to stop blinking in snake movement.

Android app for FLAMES

                                                     FLAMES Android App

=> It follows the same way just like 1]how we take two names, 2]cross the common letters of both names, 3]counting  the number of uncommon letters and then 4]striking the FLAMES with the number.

              In this post I shared both MainActivity.java  and activity_main.xml files.

APP URL : - https://play.google.com/store/apps/details?id=com.viswadeepgmail.l.flames

Idea behind reducing complexity of the game:-

             * complexity of the game can be reduced after finding the number of uncommon letters  i.e, last step striking the FLAMES with the number. I calculated it for 50 uncommon letters. 

             => Yes you are right once if sum of uncommon letters of both names exceeds 50 then this app is not going to work. But it is rare to find a person with name having more than 25 letters( so that sum of two leads to 50), More over there are only 26 different Alphabets only. Which means there is a very minute probability to get more than 50 uncommon letters.

Benefit by doing so :-

     => We can increase Running time(Runs fast), decreases complexity(uses less ram) and reduces memory(app occupies less space in your mobile) at same time. Mostly in any Algorithm we need to compromise at one or the another but by using above idea we can achieve it.

Specifications

Version                  :-   1.0

Memory occupied  :-    784 KB

Running Time        :-    < 1 sec

Location                :-     No need

    

NEXT VERSION :- 

 In next version I will try to extend it for persons with big names (more than 100 letters) with out getting compromised for above 3. Meet you in next version. 

                                                                                  ...................Happy Coding
