#26877 — Re: dictionary into desired variable....

Sorry,
I ment of course list....

what I exaclty ment is

that if I assign

value = Number

that I automaticly assign y[1][3][6][1][1] a new number.

more detailled explained:

let us say a would be x = [2,5,4]

y = a[3]

if I change y to []

I want the result to be x = [2,5,[]] and that's automaticly
independently how deep i dig.



Sorry for the inconvenience.


Tamer

There is no such thing as a[3] if a=[2,4,5].  And this is a list not a dictionary, so I would suggest a tutorial from the Python wiki page.

You have to use a mutable container.  Integers are not mutable.  Lists, for example are.

y=[4]
x = [2,5,y]
print x
y[0]=10
print x
