Creating and sorting a 2D array

How do you create a double-array in Sage (first component string, second component int)? And, how do you sort the double-array based on the value of the second component?

Right now, our code looks like:

G0 = []
pop = 0
while pop<1000:

G0_fit = []
for i in range (0,1000):

tempList = sorted(G0_fit)
cutoff = tempList[400]

inter = []
for i in range (0, 1000):
    if G0_fit[i]<=cutoff:

We want to avoid the "cutoff=tempList[400]" and following loop, and just sort both G0 and G0_fit in one step.

Look at the python documentation, especially at the key function.

Sorry for the delayed response. We gave it a try, and it's definitely a much more natural way to sort. Thanks!
