array of array of float

[Summercoolness at gmail.com]

i used C too much and haven't used Python for a while...

like in C, if we want an array of array of float, we use

float a[200][500];

now in Python, seems like we have to do something like

a = [ [ ] ] * 200

and then just use

a[1].append(12.34)   etc

but it turns out that all 200 elements points to the same list...
and i have to use

a = [ ]
for i in range (0, 200):
    a.append([ ])

is there a simpler way... i wonder...
