For 2021 - online Python 3 training - see ((here)).

Our plans were to retire in summer 2020 and see the world, but Coronavirus has lead us into a lot of lockdown programming in Python 3 and PHP 7.
We can now offer tailored online training - small groups, real tutors - works really well for groups of 4 to 14 delegates. Anywhere in the world; course language English.

Please ask about private 'maintenance' training for Python 2, Tcl, Perl, PHP, Lua, etc.
change the coordinates for a line

Posted by me (me), 20 January 2004
I have created a line with :
$w create line 0 50 210 50

how can I configure the coordinates for the line to be 0 60 100 40 instead?

please write the code needed

thanks

You could write

$w create line 0 60 100 40

instead, but I don't think that's what you mean .   I'm guessing that you want to change the co-ordinates of the two end points under program control.   If you want to do this at the time you're originally drawing the line, you can use variables in place of the co-ordinates that can change.  If you want to change them later, they you'll want to use tags and groups.

If you can clarify which of my guesses is correct (or put me right if I've missed the point completely) I'll post a follow up ... but please don't expect me to write a complete solution as this forum is really intende to help you learn and then write your own solution.
