[Tutor] add to list
chat_window_char_definition = { 2.7.1. : 1,
2.3.3.3.3. : 2,
2.2.3.3.4. : 3,
2.2.2.7.1. : 4,
4.3.3.3.4. : 5,
}
how do I automatically add to this list without doing it by hand?
Also, the list is of tuples of 2, how ever, I need to have a tuple of 3, is
that possible?

Is there some pattern to the values? I can't see it.

Tuples can be whatever length you want. But what you have is not a list
of tuples, it is a dict mapping keys to values. You could make the keys
or the values be tuples of strings rather than strings.
Some context would probably help us give you a better answer.

Re: [Tutor] add to list
there is no pattern in the numbers. but don't worry about it, because all i
am doing is this:
two strings that look like 2.3.3.3.3., youknow, str(int) + . +
str(int) + . and so forth
are presented and they equal to a value, which is the third string.
in short, given the first two strings, return the third string from the
list.
it's a dictionary.

Then how do you expect to create them automatically? I don't understand
that part of the question.

That sounds like you want a dict whose key is a tuple of the first two
strings, and the value is the third string. For example,
In [11]: d = { ('a', 'b'): '1',
: ('c', 'd'): '2' }
In [12]:
In [12]: d['a', 'b']
Out[12]: '1'

Re: [Tutor] add to list
Another part of program takes care of that patternless stuff, only saving
and retrieving for comparison is concerned for this part of the code.
In [11]: d = { ('a', 'b'): '1',
: ('c', 'd'): '2' }
In [12]:
In [12]: d['a', 'b']
Out[12]: '1'
that does look like what I looking for, how does it work?
