infile=open("python_07_04.txt",'w')

test_dict={'Q':1}

while(test_dict['Q']==1):
    subject=input()
    score=input()
    test_dict[subject]=score


test_dict.pop('Q',None)
total = 0

for a in test_dict:
    infile.write(str(a+' : '+test_dict[a]+'\n'))
    total+=float(test_dict[a])

infile.write(str("total = {}\n".format(total)))
infile.write(str('avg = {}\n'.format(total/(len(test_dict)))))

infile.close()
outfile=open("python_07_04.txt",'r')
text=outfile.read()
print(text)

outfile.close()
