phpoffice/phpspreadsheet

phpoffice/phpspreadsheet is a successor of phpExcel. We recently developed an automated solution to pull all the backup success rate reports from Dell EMC Data Protection Advisor (DPA). The portal which displays the report was good but not enough to use that information further like sharing the reports, pivoting etc..

After trying several methods, found this library to be very useful. There aren’t many examples available on the internet to retrieve data from MySQL and write to XLSX file. Hope this blog might be helpful who would like to use this library for creating XLSX files. Fear not, it doesn’t throw errors while opening this file in MS Office Excel

Python’s sh Library

Wish you all Happy, Prosperous & Pythonic New Year 2019!!

I thank everyone for stopping by my blog for 15K times in 2018 which is the highest so far! 

“Looking back at my life’s voyage, I can only say that it has been a good trip.” ~ Ginger Rogers

Similar to the above quote, I’d started my scripting voyage by writing shell, batch and Perl scripts in good old days. I miss some of the awesome, builtin & yet simple to use features available in shell. I felt using those features or builtins would make my life easier while writing scripts in Python…

Besides that, one main reason to look back at the past was while imparting the Python Workshop at my office. One of the participants raised concerns over Python’s builtin modules like OS and Subprocess. They mentioned we can accomplish with very simple steps in ‘Shell’ instead of using OS or Subprocess module. I had to accept the fact that sometimes Python is not so easy as we think!

After googling for a while I finally found this… Say hola to ‘sh‘ Module!

The ‘sh’ library provides simple and intuitive alternative to OS/System/Subprocess modules.

‘sh’ module simplifies Python’s ability to interact with native OS by calling shell commands. This would greatly helps in automation of routine tasks and running sequence of commands, parsing output as per requirement.

Python is a powerful language powered by those great developers who are continuously contributing to enable new features every day in day out. I would like to thank Andrew Moffat for the ‘sh’ library. This library is one of my favourites.

To install this library using PIP, run below command

pip3 install sh 

Please find sample scripts output. 

>>> import sh

>>> sh.uname()

Darwin

>>> sh.uptime()

 7:13  up 11 days, 23:29, 4 users, load averages: 1.51 1.65 1.88

>>> 

>>> sh.echo(‘Hello, This is shell\’s echo running from Python’)

Hello, This is shell's echo running from Python

>>> sh.who()
