Adding updating values in python dictionarys

» corwinte: Ashar Delivery (64) to Rhad / Set Fee: 31895 CR  Oct 26th 01:12 pm

I am just learning python,so here is my rough code,it does not do all I want it to do,but it does some,and somethings not properly.

First, we are not interested in lines that begin with dates so we just ignore those. What I want is,for the code to go through the text files,gather all the names along with their credits(CR) values,calculate a percentage of each and store the total with the name.

So far, I have been able to ask the percentage,gather the names and get percentage of all entrys,not total.

Here is my code.

inp = input('enter the name of the file to be opened\n') #asks for a file,opens it,a guard to handle misspelled or files that don't exist
try:
    fhand = open(inp)
except:
    print('Are you on medications? there is no',inp)
    exit()
per = input('Enter the percentage you would like to calculate from,percentage of the fees recieved')
perc = float(per)
for line in fhand:
    if not line.startswith('»'): continue
    words = line.rstrip().split() #stripping the right spaces and splitting into words
    feesrecieved = words[-2]
    actam = float(feesrecieved)*perc/100
    print(words[1], actam)

How do I get it to say,give me total calculated value of each name? I.E all dragons hauls,all dagons hauls and so on. Thank you!

I think I understand your question. I would add it to a dict and update the values as I go along.

per = input('Enter the percentage you would like to calculate 
from,percentage of the fees recieved')
perc = float(per)
totalFees = {} // create empty dict
for line in fhand:
    if not line.startswith('»'): continue
    words = line.rstrip().split() #stripping the right spaces and splitting into words
    feesrecieved = words[-2]
    actam = float(feesrecieved)*perc/100
    print(words[1], actam)
    totalFees[words[1]] = totalFees.get([words[1], 0) + actam //updating dict

you can either add after finding the percentage or before and caculate the total at the end
