Sorting dictionaries (code example)

Something I use: b = j.cos.items() b.sort(lambda a, b: cmp(b[1],a[1])) # sort by value. [0] would be the key b = b[:50] # get top fifty values j.cos = dict(b) Really badly highlighted with:

source-highlight -spython -fxhtml sort.py

Try use the Basic style sheet?
