I have tried to understand problem number 6 (below) from quiz 1. I dont understand what "d.keys()" does/mean? I dont get d[k] = 0 means? Is k indexing to 0? I dont understand why d2 has d2 in one of the parameters. def f(s, d): for k in d.keys(): d[k] = 0 for c in s: if c in d: d[c] += 1 else: d[c] = 0 return d def addUp(d): result = 0 for k in d: result += d[k] return result d1 = {} d2 = d1 d1 = f('abbc', d1) print addUp(d1) d2 = f('bbcaa', d2) print addUp(d2) print f('', {}) print result 6.1) What does it print?
