Hello

I receive such error:
File "p4.py", line 24, in PrintWordCountFloat
print "%s %f" % (word,words[word])
TypeError: list indices must be integers

i call PrintWordCountFloat with hash table, keys are words(string) and
values float.
This part of the code:

def PrintWordCountFloat(words):
number = 0
for word in words:
print "%s %f" % (word,words[word]) #line 24
number = number + 1
print "Total words: %d" %(number)

My function displays whole table correctly, and after that i receive
mentioned error.
Why ? Where is the problem ?

Thanx

Perhaps you meant something more along the lines of this:

number = 0
for index, word in enumerate(words):
print "%s %f" % (index, word)
number = number + 1
print "Total words: %d" %(number)

0 0.000000
1 1.000000
2 2.000000
3 3.000000
4 4.000000
5 5.000000
6 6.000000
7 7.000000
8 8.000000
9 9.000000
Total words: 10

Or similar; I can't read your mind. Just know that enumerate(iterable)
yields (index, value) for each item in iterable.

Thanx

words is a list. If your variable names mean anything, I presume that
word is ... well, a word, thus a string. But you can't do

[1,2,4]['some_word']

That only works on dictionaries, like this:

{'some_word' : 100}['some_word']

You could be calling PrintWordCountFloat() twice, once with a dictionary and
then with a list :-)

If I'm wrong, you have to provide more code.

sorry, i was not precise. words is a dictionary.
1. How can i show it's all variable (with key and value) ?
2. How can i show sorted dictionary (by key) ?
3. Is there any function which could do fast iteration on elements of
sorted dictionary ?

Thanx

I hope this helps a bit:
