Making a Bottle app with Python Tutorial Part 1 - Introduction

When I was introduced to bottle framework I was amused by its simplicity. It is really one of the best python web frameworks available today. It is really simple that even a beginner in python will be able to create website on the go. According to me if you were to create some small web app then Bottle is the best python framework. 

Before we start let us see what bottle framework is:
  • It was created by Marcel Hellkamp. 
  • According to the website bottle started as an experiment and now it has a very large support because of its simplicity.
  • Bottle is simple, fast and light weight WSGI  micro web framework made with python. 
  • It is only single file and thus you can use it directly.
  • It doesn't depend on any other libraries but the main python standard library.

Okay what are we going to make? 

We will create a web app which will return the user weather information based on the location of the user. Yes! you have read it correctly. We will find out the location of the user using our web app and return the weather data. I have named it weave. You can see the working version of the website from here: Weave.
Note: Each and everything we are going to use in this tutorial series is free and can be used for non commercial uses. 
It will look somewhat like this:
Weave - Live weather data using python bottle framework

Pre-requisites 

I have hosted this website for free from here: Pythonanywhere. But before we host our website on pythonanywhere we will develop it on our local computer and then we will upload the same by making small modifications. So I would like to suggest you to create an account at pythonanywhere so that you can directly upload the website after it has been created.

Next to get the live weather data we will be using openweathermap website api. But you will have to signup to get their api key. 

Note that I will be using '######' to represent my api key in the code.

Also to find out the user location we will be using ipinfoDB which will find out the user location based on the ip address. They to have their own api key to use their data. So I suggest you to create an account at ipinfoDB so that we can use their data to find the user location. I will be using "######" to represent my api key in the code.

If you don't want to use ipinfodb, then you can use another free api from freegeoip.net and the api is free for everyone and you don't have to signup, you can use it directly. You can find the json data from here: freegeoip.net/json. 

But I will be using ipinfodb for this tutorial. If you are new using API with python then you will have to follow along with me and then after the tutorial is complete you can come back use your own API key. After this tutorial you will be comfortable making use of API keys.

Please do remember that all the above stated API keys are free and I suggest you not to pay any money for anything atleast for now. Make use of free and opensource projects to learn. Once you have learnt how to make use of these kind of API keys then you can buy API keys for any larger projects you will do in future if required.

If you want to know more about what an API is then I would suggest you to see this  What is an API? which has lots and lots of answers which the beginners can understand easily. I think this will help you. 

Okay that's all for this post I will meet you in the next post.

Project Euler Problem 67 Solution with Python

Maximum path sum II By starting at the top of the triangle below and moving to adjacent numbers on the row below, the maximum total from top to bottom is 23. 3 7 4 2 4 6 8 5 9 3 That is, 3 + 7 + 4 + 9 = 23. Find the maximum total from top to bottom in triangle.txt (right click and 'Save Link/Target As...'), a 15K text file containing a triangle with one-hundred rows.

Problem 43 Project Euler Solution with python

Sub-string divisibility The number, 1406357289, is a 0 to 9 pandigital number because it is made up of each of the digits 0 to 9 in some order, but it also has a rather interesting sub-string divisibility property. Let d 1 be the 1 st digit, d 2 be the 2 nd digit, and so on. In this way, we note the following: d 2 d 3 d 4 =406 is divisible by 2 d 3 d 4 d 5 =063 is divisible by 3 d 4 d 5 d 6 =635 is divisible by 5 d 5 d 6 d 7 =357 is divisible by 7 d 6 d 7 d 8 =572 is divisible by 11 d 7 d 8 d 9 =728 is divisible by 13 d 8 d 9 d 10 =289 is divisible by 17 Find the sum of all 0 to 9 pandigital numbers with this property. One might write a simple solution using direct if else statements for this problem. Using if else statements, the execution time may be a few seconds. But this is not a very good approach. I too had written a program with if else statement which will take each and every permutation of the 0-9 Pandigital and check for the conditions given in the qu...

Add/Embed SVG to Blogger website

In this post I will tell you my method(trick) of adding SVG images in a blogger website or blog. Before starting , the first thin g I am assu m ing is that you are aware of SVG if you are here. If not please see S calable V ec tor G raphics Recently when I tried to embed a SVG image for a post on pygal, I tried uploading the SVG file and blogger Image uploader came up with an error, because of which I had to find some other way.  SVG File upload Error in Blogger  I started sea rc hing Google " Embed SVG in Blogger " . I found blogorrhea , w h ich gave some i nformatio n on add ing SVG directly as a markup , which worked , but I faced another problem using this . Also th is guy has used lot of Javascript which was confusin g for me, being new to using SVG.   So I first t houg ht of learning on h ow to embed SVG in HTML and t his on e worked out.
