Hi I have been working on a homework assignment that I am having a lot
of trouble with. I am so frustrated because every time I think I am
getting close to figuring it out there is another problem. If you
could look at this and tell me what I am doing wrong I would very much
appreciate it....
import string
from datetime import date
class Leaderapplicant:
def __init__(self, line):
#convert the lines of data into fields and removes
\n
line = line.rstrip("\n")
appname, leadername, start, end = line.split("\t")
self.appname = appname
self.leadername = leadername
yyyy, mm, dd = start.split(",") #splits the string
into dates
b = int(yyyy)
c = int(mm)
d = int(dd)
self.start = date(b,c,d)
yyyy, mm, dd = end.split(",")
b = int(yyyy)
c = int(mm)
d = int(dd)
self.end = date(b, c, d)
def getAppname(self):
return self.appname
def getLeadername(self):
return self.leadername
def getStart(self):
return self.start
def getEnd(self):
return self.end
def getSomething(self):
# infoStr is a tab separated line: name leadername startdate
enddate
return self.appname + "\t" + self.leadername + "\t" +
self.start + "\t" + self.end
#import Leader Applicant
def get_files():
infile = raw_input("What file is the data in? ")
outfile = raw_input("What file would you like the data to go
in? ")
return infile, outfile
def main():
#recall get_files function
files = get_files()
#open files
infile = open(files[0], 'r')
outfile = open(files[1], 'w')
reportstart = raw_input("Please enter the date (yyyy, mm, dd)
the reporting period started: ")
yyyy, mm, dd = string.split(reportstart, ",")
yyyy = int(yyyy)
mm = int(mm)
dd = int(dd)
reportstartdate= date(yyyy, mm, dd)
reportend = raw_input("Please enter the date (yyyy, mm, dd)
the reporting period ended: ")
yyyy, mm, dd = string.split(reportend, ",")
yyyy = int(yyyy)
mm = int(mm)
dd = int(dd)
reportenddate = date(yyyy, mm, dd)
for line in infile:
a = Leaderapplicant(line) #from data file
if a.getEnd() >= reportstartdate and a.getEnd() <=
reportenddate:
outfile.write(a.getAppname())
outfile.write
("\n")
#close files
infile.close()
outfile.close()
#print "The list has been written to", files[1]
if __name__ == '__main__':
main()
I am using tab separated data in another file that looks like this...
appname1 leadername1 2005, 02, 02 2006, 02, 02
appname2 leadername2 2006, 03, 21 2007, 06, 28
etc...
The error message looks like this....
back (most recent call last):
File "/home/amy/Documents/LIS452/assignment 3/testworks.py", line
97, in <module>
main()
File "/home/amy/Documents/LIS452/assignment 3/testworks.py", line
80, in main
a = Leaderapplicant(line) #from data file
File "/home/amy/Documents/LIS452/assignment 3/testworks.py", line 9,
in __init__
appname, leadername, start, end = line.split("\t")
ValueError: need more than 3 values to unpack
Any help would be greatly appreciated. I have spent so much time on
this that I am behind not only in this class but in other classes as
well.
