Hi everyone. I have a file of records like this:
ID:13
Date: 12.12
Scores: 2
ID:22
Date: 9.12
Scores: 4
ID:13
Date: 18.12
Scores: 4
I want to have the unique IDs as keys and the sum of the socres for that ID as values in the scoreDict dictionary. This is my code so far: - if ID is not None:
-
if ID not in scoreDict:
-
scoreDict[ID] = set()
-
scoreDict[ID].add(Scores)
-
ID = None
I want to have for example for person with ID 13 a sum of all her goals. How do I do the summation inside that piece of code? Any guide or help is appreciated.
Best regards, Atrisa

All that is required is an integer that holds the total. Also, you do not need
if ID is not None:
as long as "None" is not in the dictionary. - if ID not in scoreDict:
-
scoreDict[ID] = 0
-
scoreDict[ID] += score
Thanks dwblas. For some reason it kept telling me that score is not defined, though it is. After making some changes, now the working code looks like this: -
scoreDict.setdefault(ID, 0)
-
scoreDict[ID] += int(score)
thanks a lot again,

Because score probably isn't defined. From your original code, it looks like you have a variable called scores but not score.

If you want to keep the individual scores in the dictionary in some future program, use a list instead of a set. A set does not allow duplicate entries, so if you have 2 scores that are the same for any key, only one will be in the set.

What's a good way to compare values in dictionaries? I want to find

I'd like to find a .NET Collection in which I will be able to set many

Hello,
I was trying to create a flattened list of dictionary values where each
value is a list, and I was hoping to do this in some neat functionally
style, in some brief, throwaway line so that it would assume the
insignificance that it deserves in the grand scheme of my program.
I had in mind something like this:

I'm not sure if I'm calling the right method in a dictionary. I have:

print NT

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
