<div class="moz-text-flowed" style="font-family: -moz-fixed">Hello all,
Thank you all for your help. I appreciate it alot.
I have been trying to work with file IO alot recently and would like
to improve my little program so that I no longer use a hard coded
list, but a text file that I can edit easily.
The text file is three lines long and looks exactly like this:
Reminder1,2009_10_28
Reminder2,2009_11_01
Reminder3,2009_11_15
My program consists of the following code:
============
#]------------------[import modules]------------------[
from time import strftime, mktime, localtime
from WConio import textcolor
#]--------------------------------------------------------[
#]------------------[define functions]------------------[
def read_reminders():
print "\nReading text file into program: reminders.txt"
text_file = open("reminders.txt","r")
reminders = [line.strip().split("'") for line in text_file]
text_file.close()
print reminders
#
def get_computer_date():
#Get today's date from the computer
todays_date = strftime("%Y_%m_%d")
return todays_date
#
def color_print(strings):
#Change the text color in the WinXP dos shell
#The way to use:
#color_print([("string",color number),\
#(str(variable),color number),(etc)])
for string in strings:
textcolor(string[1])
print string[0],
#
def change_to_julian(reminder_date):
#Receives the year, month, and day
#in the form of a single string (2009_10_15)
#and changes it into three different int
#variables. Then take those three variables
#and append six zeros and change into a
#julian date.
date = []
date = reminder_date.split("_")
year = int(date[0])
month = int(date[1])
day = int(date[2])
timetuple = (year, month, day) + ( (0,) * 6 )
unixtime = mktime(timetuple)
timetuple = localtime(unixtime)
print days_left(timetuple[7])
# [7] is the number of julian-date field of
#the unixtime tuple.
return days_left(timetuple[7])
#
def days_left(julian_date):
#This function calculates the days left
#until a reminder. If the days left are
#greater than 0 it will print normally.
#If it is -1 then it will print differently.
#Also if it is greater than -1 it will print
#yet again differently.
days_until_reminder = julian_date - localtime().tm_yday
if days_until_reminder > 0:
color_print ([("There
are",7),(str(days_until_reminder),4),("days left until this
reminder.",7),("\n",7)])
elif days_until_reminder == -1:
color_print ([("\tYou have missed this reminder
by",4),(str(days_until_reminder*-1),4),("day!",4),("\n",7)])
color_print [("
------------------------------------------------------------------------",4),("\n",7)])

color_print ([("\tYou have missed this reminder
by",4),(str(days_until_reminder*-1),4),("days!",4),("\n",7)])

#
def compare_reminders(todays_date):
#This function compares the reminders
#to the computer date.
#It has three different paths:
# 1.Matches today's date
# 2.The reminder date has already
# passed by
# 3.The reminder date is yet to
# come.
#After determining which it is it will
#access the change_to_julian and
#days_left functions.
#reminders.sort()
color_print ([("
[-------------------------------------------------------------------------]",4),("\n",7)])
index = 0
while index < len(reminders):
if todays_date == reminders[index][1]:
print
color_print [("
------------------------------------------------------------------------",4),("\n",7)])
print "Today's reminder is:
",reminders[index][0],"on",reminders[index][1]
color_print ([("\t\tTake care of this reminder
immediately",2),("\n",7)])
elif todays_date > reminders[index][1]:
print
print "Whoops, you missed the following
reminder.",reminders[index][0],"on",reminders[index][1]
change_to_julian(reminders[index][1])
else:
print
print "Your upcoming reminders are:
",reminders[index][0],"on",reminders[index][1]
change_to_julian(reminders[index][1])
index = index + 1
color_print ([("

#]--------------------------------------------------------[
#]-------------------[Main Program]-------------------[
read_reminders()

#]--------------------------------------------------------[
============
Could someone explain to me why my read_reminders function retrieves
the information, but cannot process that information?
When I try and run the program I get the following error message:
============
Reading text file into program: reminders.txt
[['Reminder1,2010_10_15'], ['Reminder2,2010_11_01'],
['Reminder3,2010_11_15']]
Traceback (most recent call last):
File "reminders.py", line 182, in <module>
print reminders
NameError: name 'reminders' is not defined
============
Thanks in advance for your help,
Katt
The function read_reminders() doesn't return anything, so once it's
done, those reminder items are gone. It printed them, then forgot them.
Similarly, compare_reminders() tries to work on reminders, when it was
not passed the data either.
You need to add a return statement to read_reminders(), and when you
call it, you need to save it somewhere. Then you can pass it to the
compare_reminders() function so it has something to compare with.
Once you get that sorted out, another bug that's already apparent is
that you're trying to split the line on quotes, when it uses commas
between fields on each line.
