reminders is a local variable which is only available within you
read_reminders function
you can return the results instead to be used elsewhere
EX:
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()
return reminders
#]-------------------[Main Program]-------------------[
reminders = read_reminders()
print reminders
compare_reminders(get_computer_date())
pause_it = raw_input("Press a key to end: ")
#]--------------------------------------------------------[
