Running .Py files in Windows

By -
This blog is meant to act as a programming diary and solutions to the problems that I encountered while learning . I hope that this blogs provides help to my fellow programmers, too.

 Currently trying to learn Python and improve my programming skills as well. I'm following Google Code Python classes for this purpose. While trying to run .Py files in Windows using Git Bash, I encountered the following error - sh.exe": python: no such command. To resole this problem, I did what I always do that is I googled it. And I found the following solution which I will now share with you all.

  As per the solution I found, courtesy of stackoverflow.com, this error means Git Bash does not know where your python.exe is. It searches your normal windows search path, the PATH environment variable. You're probably failing the 4th step on the instructions already "Make sure Python is working in the Git Bash":

 

$ python --version
sh.exe: python: command not found


 To fix that, append C:\Python27 (or wherever you installed python) to your PATH environment variable in windows. You need to restart the bash after this for the change to take effect. This will allow you to run python from the windows command prompt as well.
And to set the path and environment variables in Windows 7, follow the following steps:
1. From the Desktop, right-click My Computer and click Properties.
2. Click Advanced System Settings link in the left column.
3. In the System Properties window click the Environment Variables button.



For those who don't want to alter your windows PATH variable or make python only available to git bash, you could create a .bashrc file in your %USERPROFILE% directory and set the variable there:

C:\>notepad %USERPROFILE%\.bashrc

and add

export PATH=/c/Python:$PATH

to the file. That script is executed every time you start the git bash and prepends C:\Python to git bash's PATH variable, leaving the system-wide PATH variable untouched.

Now that you know what has to be done, you can use this shortcut on the bash instead (appends the export command to your .bashrc)


$ echo export PATH=/c/Python:\$PATH >> ~/.bashrc
I have tried the changing the windows PATH solution and it works perfectly. Hope, this solutions helps you, too. 
Have a good day!!

Project Wild Penguin 22.4.2017: To delete directories inside current directory whose contents are less than a given size

By -
With GNU find and GNU coreutils, and assuming your directories don't have newlines in their names: find . -mindepth 1 -maxdepth 1 -type d -exec du -ks {} + | awk '$1 <= 50' | cut -f 2- This will list directories with total contents smaller than 50K. If you're happy with the results and you want to delete them, add | xargs -d \\n rm -rf to the end of the command line. Command: find . -mindepth 1 -maxdepth 1 -type d -exec du -ks {} + | awk '$1 <= 50' | cut -f 2- | xargs -d \\n rm -rf Source:  https://unix.stackexchange.com/questions/214089/command-to-delete-directories-whose-contents-are-less-than-a-given-size

ANPR Project Day 1: Standard Format of Indian Number Plate

The main purpose of ANPR project is to recognize the characters present in the number plate. To do this first, understanding the standard format of Indian Number Plate is required.  Since June 1, 2005, the Government of India has introduced High Security  Registration (HSR) number plates which are tamper proof. All new motorized  road vehicles that come into the market have to adhere to the new plates, while  existing vehicles have been given two years to comply with. Features  incorporated include the number plate having a patented chromium hologram; a  laser numbering containing the alpha-numeric identification of both the testing  agency and manufacturers and a retro-reflective film bearing a verification  inscription "India" at a 45-degree inclination. The numbers would be embossed  on the plate, rather than being painted for better visibility. The term "India" is to  be in a light shade of blue.  But still most of the vehicl...
