[Tutor] help on dic creation

[Brayden Zhao]

hello! 

I am doing my homework now and I am kinda stuck. Could any of you help me out? 


Here is the homework problem:

 fieldict(filename) reads a file in DOT format and 
      returns a dictionary with the DOT CMPLID, converted to an
      integer, as the key, and a tuple as the corresponding value
      for that key.  The format of the tuple is:
         (manufacturer, date, crash, city, state)
      where these tuple items have the following types:
         manufacturer -- this comes from the MFR_NAME field in the DOT format 
	 date -- this comes from the FAILDATE field in the DOT format, 
	         but converted to a Python datetime.date object
	 crash -- this comes from the CRASH field in the DOT format, 
	         but converted to a Python bool type (True for a crash)
         city -- comes from the CITY field in the DOT format
	 state -- comes from the STATE field in the DOT format
should return: fieldict("DOT500.txt")[82]
  ('FORD MOTOR COMPANY', datetime.date(1995, 1, 1), False, 'MARBLE HEAD', 'MA')


and here are parts of the data:

1	958164	TOYOTA MOTOR CORPORATION	TOYOTA	LAND CRUISER	1994		19941223	N	0	0	SERVICE BRAKES, HYDRAULIC:ANTILOCK	ARNOLD      	CA	JT3DJ81W8R0	19950103	19950103			ABS SYSTEM FAILURE, AT 20MPH.  TT	EVOQ																									V

Here is my code and I dont know why my code is only reading the 500th line of the file. Thanks for your help! 


import datetime
def boolean(S):
  if S=="Y":
    return True
  return False

def fieldict(filename):
  D={}
  with open(filename) as FileObject:
    for lines in FileObject:
      linelist=lines.split('\t')
      Key=linelist[0]
      ValCity=(linelist[12]).strip()
      ValState=linelist[13]
      ValOne=linelist[2]
      ValTwo=linelist[6]
      ValThree=boolean(linelist[7])
  D={Key:(ValOne, ValTwo, ValThree, ValCity,ValState)}
  return D
print fieldict("DOT500.txt")
