Formatting options in Python

For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))

Take a look at this program run:

  munchkin:n13py grahamellis$ python twoforms 

  

  There is a large piece of timber in the back garden

  and the dog was sniffing around it earlier. It looks like it was left

  there by the storm that came our way last night.

  

  There is a large piece of plastic tape in the back garden

  and the fuzz was sniffing around it earlier.  It looks like it was left

  there by the graverobber that came our way at Halloween.

  munchkin:n13py grahamellis$

I've used two - of many different - possible ways of formatting text in the block above; the program is [here]

Python is a strong text handling language - above example was written on Friday a a demonstration to show a customer how his code could be improved by moving from the first formatting method, where the place holders were a long way from the content ant it was very hard to correlate, to the second format with named place holders.

This is a page archived from The Horse's Mouth at http://www.wellho.net/horse/ - the diary and writings of Graham Ellis. Every attempt was made to provide current information at the time the page was written, but things do move forward in our business - new software releases, price changes, new techniques. Please check back via our main site for current courses, prices, versions, etc - any mention of a price in "The Horse's Mouth" cannot be taken as an offer to supply at that price.
