Hi!
I can also put more than 4 million entries *into* the dictionary. But I can
only get less than 65.000 back out!
What do you get with: len(dict.keys()) ?
And with a loop like
count = 0
for elem in dict:
count = count + 1
print count
The keys are ordinary words like an ordinary dictionary :-) with an average
length of about 6 characters.
