help - python question

[funkky]

Please 'am a new beginnger in python. I have been trying to solve these problems, but 'am always getting stuck. Can you please help me out:

1.

 numBuckets = 8
buckets = [0] * numBuckets
bucketWidth = 1.0 / numBuckets
for i in range(numBuckets):
      low = i * bucketWidth
      high = low + bucketWidth
      buckets[i] = inBucket(list, low, high)
print buckets

the output suppose to give me values, after running the program, I kept getting this:

>>>[none, none, none, none, none, none, none, none]

2.

 numBuckets = 8
buckets = [0] * numBuckets
for i in list:
      index = int(i * numBuckets)
      buckets[index] = buckets[index] + 1

I am using python 2.5.1 version

1: You'll need to include the inBucket function.
2: I'm not sure what you are trying to do, but this may give you some clues to both problems:

numBuckets = 8
buckets = [0] * numBuckets
 
def ChangeBucketsInPlace():
    for i in range(numBuckets):
        index = int(i * numBuckets)
        buckets[i] = index
 
 
print buckets
ChangeBucketsInPlace()
print buckets

I'm guessing your following the code from the site at How to Think Lika a Computer Scientist: Chapter 9. Post of the code, so we can see the values of the list and the definition of the inBucket function, there might be some typos or something like that
