Sorting Driving Crazy: URGENT: PLEASE HELP

[dont bother]

This is really driving me crazy.

I have a dictionary feature_vectors{}. I try to sort
its keys using

#apply sorting on feature_vectors
sorted_feature_vector=feature_vectors.keys()
sorted_feature_vector.sort()

#feature_vector.keys()=sorted_feature_vector

new_feature_element={}
new_feature_vector={}

for x in sorted_feature_vector:
    print "SORTING\n"
    print x, '\t',feature_vectors[x]
    count=0
    if(count==0):
        new_feature_element=str(1)+"
"+str(x)+":"+str(feature_vectors[x])+" "
    else:
       
new_feature_element=str(x)+":"+str(feature_vectors[x])+"
"
        count=count+1
       
new_feature_vector=str(new_feature_vector)+str(new_feature_element)
        new_feature_vector=new_feature_vector+"\n"
    
print "New Dictionary"


When I print x and feature_vectors[x]  I get some of
the entries which are not in the increasing order.

This should not happen but why is this happening and
how to fix this.

My problem is given a dictionary, sort the keys and
have a new dictionary with the key, values where the
keys are in increasing order.

I would be really grateful if anyone can help me out

Thanks
