KeyError: 3 problem

[GTXY20]

Hello,

Any comments on the below mentioned problem are most appreciated.

I have a function and it is throwing this error:

FEXpython_v2.py", line 32, in UnitHolderDistributionqty
    count[item]+=1
KeyError: 3

This is the function:

def Distributionqty(dictionary):
    holder=list()
    held=list()
    distqtydic={}
    count={}
    for key in sorted(dictionary.keys()):
        holder.append(key)
        held.append(len(dictionary[key]))
    for (key, value) in map(None, holder, held):
        distqtydic[key]=value
    for item in distqtydic.values():
        count[item]+=1
    for k,v in sorted(count.items()):
        fdist=k
        qty=v
        print fdist,qty

Not sure why.

You need something like this:

for item in distqtydic.values():
    if distqtydic.has_key(item):
        count[item]+=1
    else:
        count[item] = 1

Going back to your first lesson, your keys are strings (as in '3'), if you haven't changed things too much since then. In that case, you'd use:

count[str(item)]+=1

but I don't recall at this moment if the what type target value is. If it is an int, it may or may not (don't recall) be passed by reference. If you can give a sample of the argument, that would help a lot.

Hi.

I was able to work out with the following:

def UnitHolderDistributionqty(dictionary):
from collections import defaultdict
    count=defaultdict(int)
    for item in dictionary.values():
        count[len(item)]+=1
    for k,v in sorted(count.items()):
        fdist=k
        qty=v
        print fdist,qty

Thanks again.
