You are correct it is not. :) You code is overly complex making it harder
to understand. Try and reduce the problem to the least number of tasks you need.

mentality.
1. function that returns the loaded book
def load_book():
load_book = open('c:/Python27/Toli/myfile.txt', 'r')
load_book = eval(load_book.read())
return load_book!
2. A system to navigate your program.
def mmenu():
# load tbook here
while True:
choicem = get_menu_choice()
if choicem == 'e' or choicem == 'E':
book = get_book_name()
edit( tbook, book )
elif choicem == 'd' or choicem == 'D':
book = get_book_name()
details( tbook, book )
elif choicem =='Q' or choicem == 'q':
break # end loop to exit program
else:
print 'Selection {0} not understood.'.format( choicem )I have
given you more functions
3. function to write an edited book
def write_book(tbook):
write_book = open('c:/Python27/Toli/myfile.txt', 'w')
write_book.write(str(tbook))
# I think repr would be more accurate than str here.
4. Function to print the entire book
def listpb( tbook ):
print '_' *45, ' Phonebook ', '_' *45,'\n\n\n'
print 'Nick\t\tF.Name\t\tL.Name\t\tCity\t\t\tRegion\t\tTel'
print '_' * 105,'\n','\t' * 13
for val in tbook.keys():
print val, '\t\t', tbook[val][0], '\t', tbook[val][1], '\t',
tbook[val][2], '\t\t', tbook[val][3], '\t\t', tbook[val][4],'\t\t\n'
print '_'*105,'\n\n'
5. Get input from user
def get_menu_choice():
choice = raw_input('input: ')
return choice
6. A function to get book name from user
def get_book_name(tbook):
# write this and do not use global
6. A function to print an entry from the book
def details( tbook, choice ):
# write this, no menu interaction allowed
7. A function to edit an entry from the book
def edit( tbook, choice ):
# write this, no menu interaction allowed
# you can ask the user what you need to change the values
I do not think you need any other functions. Now you just need to finsh all the
functions
and put it all together.
