python - Calculating average grade wont succeed -

i have calculate average grade of person in python. received input file , in combination that, have calculate everyones average grade. tried lot, got average grade of first person.. can me?

the input file following:

tom bombadil__________6.5 5.5 4.5 dain ijzervoet________6.7 7.2 7.7 thorin eikenschild____6.8 7.8 7.3 meriadoc brandebok____1.0 5.0 7.7 sam gewissies_________2.3 4.5 6.7 

the output follow:

tom bombadilhas average grade of 5.5 dain ijzervoethas average grade of 5.5 thorin eikenschildhas average grade of 5.5 meriadoc brandebokhas average grade of 5.5 sam gewissieshas average grade of 5.5 

i used code:

def names(lines):     in lines:         invoer_split = i.split("_")         first_name = invoer_split[0]         print first_name + "has average grade of %.1f" %(average_grade(names))  def average_grade(names):     in lines:         grades_split = i.split("_")         grades = grades_split[-1]         grades_float = map(float,grades.split())         grades_average = sum(grades_float)/3         return grades_average  grades_file = open('grades1+2.in') lines = grades_file.readlines()  names(lines) average_grade(names) 

instead of processing names , grades separately, them @ same time. change input dictionary mapping strings float.

with open('filename') f:     grades_dict = {}     line in f:         name, *underscores, grades = line.split('_') #i forget when syntax became thing.  might have assign these separately         grades = list(map(float, grades.split()))         grades_dict[name] = sum(grades)/len(grades)  name, grade in grades_dict.items():     print('{0} has avergae grade of {1}'.format(name, grade))
