[Tutor] Multiple Dimension (array/list/whatever it is are).

[George Patterson]

Hi All.




A could of quick questions:

1. What is the data structure below called? Apart from G :-P  Is it an array, a list or something else. The original article was very vague on the commenting. See bottom of email for URL.

G = {'s':{'u':10, 'x':1},
     'u':{'v':1, 'x':2},
     'v':{'y':4},
     'x':{'u':3, 'v':9, 'y':2},
     'y':{'s':7, 'v':6}
    }


2. How would I alter the above data structure such that all instances of 'x' ends up being equal to 5. As per sample below.

{'s':{'u':10, 'x':5},
     'u':{'v':1, 'x':5},
     'v':{'y':4},
     'x':{'u':3, 'v':9, 'y':2},
     'y':{'s':7, 'v':6}
}
