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.
lappend huge data

Posted by dee00zee (dee00zee), 12 May 2005
let say i have a huge data
example 1 2 3 until 1000

and i want to append these data to a list.

lappend lst 1 2 3 until 1000

how to do these?
because to lappend every element until 1000 is inefficient.
any short cut to this?

Do you actually need a list?  In your example, you talk about the numbers from 1 to 1000, and if I wanted to iterate go through each of those numbers in turn I wouldn't bother with a list - I would just use a for loop and generate them "on the fly".

i want to return those number to the main program

Hmm.  I'm still don't think I'm fully with it.  If you need to return the list from a proc, then it only takes 2ms (and that's on my old laptop) to generate the list - technically inefficient perhaps but no great problem in most applications.   You could store the list in a global variable to save the need to regenerate it every time if you need to return the same list more than once.
