| | What is prefered version on handling 'serialized' code snippets, with features added to previous post? I have posted a [polynomial expression snippet](http://www.daniweb.com/software-development/python/code/425151/class-based-polynomials-with-magic-methods#post1817526) to which I could not include the division part because original poster whose thread inspired me to start, have not proved finding his solution to the problem.

| | New Daniweb way to copy the code from posts with indentation is to double click (not too quickly) to select the code region and use normal copy paste as you like (second mouse button or ctrl-c). Easier than before but little not obvious! |
| | The vanity pages to look how good and active you are compared to others is back from member's #Community Contributions part underlined links. Thank you Dani, now we know again how good we are! *P.S. How many activity points worth is giving a spammer infraction? ;)* |
| | Here is an amazing article. Peter Norvig does not let small detail, that the language was never implemented in it's time, disturb his debugging the code written without implementation, but single handedly implements it with Python parser.

| | I participated discussion about complex numbers and did some experiments in Python. I do not understand this behaviour (same behavious in 2.7.2 and 3.2.2): [CODE] >>> -(0+1j) (-0-1j) >>> -(0+1j)==-1j True >>> -(0+1j)+0 -1j >>> -(0+1j)-0 (-0-1j) >>>[/CODE] EDIT: Further investigation shows that there is -0.0 in Python, is this … |
The End.
