Problem Tester's code:
d={}
for i in range(int(raw_input())):
line=raw_input().split()
d[line[0]]=sum(map(float,line[1:]))/3
print '%.2f' % d[raw_input()]
Plz explain why float is used ? There should be a function

name, *line = input().split()
scores = list(map(float, line))
student_marks[name] = scores
query_name = input()
l=list(student_marks[query_name])
length=len(l)
s=sum(l)
average=s/length
print('%.2f'%average)
