Import sympy
I had just had a look at sympy’s documentation and it provides good support for solving differential equations. Sample this . Solving a differential equation would be as simple as this which gives f(x) == C1*exp(x) as the ouput. I also tried an example given in my book. which again gives me f(x) == C1*exp(-x) […]
Positioning of widgets in PyQt4
A short note on positioning of widgets in PyQt4 . Let say you have a layout , a button and few labels. If I press a button and a label should become invisible , your code should look something like this. The problem with this however is , it automatically repositions your labels such that […]
PyQt4 Notes – 1
Here are a few code snippets I had to search for . This is for my future reference and for any one who might needing it. 1 . First of all , a simple concept that I did not understand before. 2 . And I had just started this thing called QtGraphicsView . It […]
Runge-kutta method using Python.
My exams finally got over . I got back home and slept for a week continuously . After that I realised I had to solve a differential equation for a project . Seniors told me the Runge-kutta method is numerically the best method to find function values at a particular point provided you are given […]
Play Hangman using python
Since I was bored , I wanted to write a script to build a simple version of Hangman using PyQt4. The logic (of course) wasn’t that difficult , however finding syntax for certain parts of the program was difficult , so I thought this post should save time , for those needing the syntax as […]
Cycle Simulation – Part Two
Continuing with my previous post about cycle simulation , I will focus on the three , important gas cycles , Otto , Diesel and Dual Cycle. I used PyQt4 for the graphical user interface , and matplotlib for the simulation . This was quite easy for the following reasons: 1 . Gas cycles are those […]
Simulation of Rankine Cycle
If you are a mechanical engineer continue reading. If you are not then please still continue reading because you have taken efforts to click on the link. So coming to the point , a Rankine cycle is a cycle that according to wiki , generates 90% of the electric power across the world. Before , […]
Installing Orange in Ubuntu – 12.04
When it comes to installing a python – package in linux , most of the times you just need to do this. or you could download an archive and go to the downloaded folder and do However I faced a lot of trouble while installing the python package Orange.I downloaded the nightly builds from this […]
Automated steam tables
Okay , the code that I wrote in the previous post , sucked and it sucked badly. There were many bugs while using it , i was iterating through lists multiple times , when I could have used a simple inbuilt python module. I have revised(rewritten) the code and can be found in this gist […]
