Python dictionary syntax, need help

[Crew Reynolds]

I want to create a dictionary of note on/off timings and access it by
the name of the object. The following code works for one row.

a = "Hammer1"
b = [5,45,45,45,45,50,55,57,59,61,60,59]

notes = {a:b}
print notes["Hammer1"][3]
The problem is, I want to load the data from a file to populate
variables a and b and build a dictionary for "Hammer1" thru
"Hammer10". That way, I can stick the name of the object in the array
index and receive a list of note timings that I can index with an
ordinal as in the above example.

This is straight Python syntax but I'm hoping someone has done this or
understands the syntax better than I.

Thanks! Alternative solutions to this concept would be greatly
appreciated.

So you want something like:

Python 2.2.1 (#1, Dec 4 2002, 23:43:31)
[GCC 3.2 (Mandrake Linux 9.0 3.2-1mdk)] on linux-i386
Type "copyright", "credits" or "license" for more information.

notes={"hammer1": [5,45,45,45,45,50,55,57,59,61,60,59],

"hammer2": [25,245,245,245,245,250,255,257,259,261,260,259],
"hammer3": [35,345,345,345,345,350,355,357,359,361,360,359],
"hammer4": [45,445,445,445,445,450,455,457,459,461,460,459],
}

#let's play at indexing...
notes["hammer1"] [5, 45, 45, 45, 45, 50, 55, 57, 59, 61, 60, 59]
notes["hammer2"] [25, 245, 245, 245, 245, 250, 255, 257, 259, 261, 260, 259]
notes["hammer2"][5] 250
notes["hammer2"][10] 260
notes["hammer4"][11] 459
#what keys did we have?
notes.keys()

['hammer1', 'hammer3', 'hammer2', 'hammer4']
print "hammer:",hammer,
for note in notes[hammer]:
print note,
print


hammer: hammer1 5 45 45 45 45 50 55 57 59 61 60 59
