Let's start with some improvements for your code. def login(): # delete multiple print statements and instead print 1 multiline string print '''\ Welcome to Account System. You now have to login the user to access the account. ''' # use raw_input(prompt) for data # note: str(sys.stdin.readline()) is redundant since readline() returns string fn = raw_input( 'Please enter the customers First name') ln = raw_input('Please enter the customers Last name') for item in customer_list: if item.firstname == fn and item.lastname == ln: current_person = item print 'You have succesfully Logged in, now transfering to account systems menu\n # note that you do not need separate print statement for extra \n time.sleep(3) accountmenu() break # I added this - once match is found, stop looping # if current_person == None: # broken since indented to execute within loop # instead of after and since current_person not initialized. Replace this with below else: print 'Sorry account records are not present in system records' print 'Going back to level 1' print 'Loading, please wait ...' time.sleep(2) print '\n' welcome_verfication() # this sort of construction -- break loop on match, else do non-match action # is precisely what else-after-for is meant for. > There are many other fucntions and classes, for instance customer_list is my > list:). I don't get any errors the program just stops and qoutes me the > module. Does replacement of broken mismatch test fix problem? If not, what is last statement executed? If necessary, add print statements to determine this. 'quotes me the module': what does this mean? Terry J. Reedy
