Hi

I'm trying remove a person from a list but it's not working.
How can I make it work, please help me.

def RemoveName(self):
lastname = raw_input("Enter the last name of the person you want to remove ")
for i in list_1:
if lastname == i.lastname:
list_1.remove(i)
print "Removed", i.name, i.lastname
return
else:
print "The name doesn't exist."

I didn't have time to test this, but it shows you some good tricks.
In your next post, please USE CODE TAGS as described in "posting guidelines", found in the panel on your right when you are posting or in the sticky thread (at the top of this forum). Your post should look like this:

def RemoveName(self):
    lastname = raw_input("Enter the last name of the person you want to remove ")
    # Search a list containing full names
    for i, full_name in enumerate(list_1):
        if lastname in full_name:
            list_1.remove(i)
            print "Removed", i.name, i.lastname
            return
        else:
            print "The name doesn't exist."

Hi

def RemoveName(self):
    lastname = raw_input("Enter the last name of the person you want to remove ")
    for i in list_1:
        if lastname == i.lastname:

            print "Removed", i.name, i.lastname
            return
        else:
            print "The name doesn't exist."

Try something like this:

name_list = ["John Smith", "Bob Jones", "Bill Sanders"]
for i in range(len(name_list)):
    if "Smith" in name_list[i]:
           del name_list[i]
        break
print name_list
['Bob Jones', 'Bill Sanders']

or this:

for i in range(len(name_list)):
    if name_list[i].split()[1] == "Smith":
           del name_list[i]
        break

or this:

import string
name_to_remove = "SMITH"
for i in range(len(name_list)):
    if string.lower(name_list[i]).endswith(string.lower(name_to_remove)):
        del name_list[i]
        break

one more:

>>> import string
>>> name_to_remove = "SMITH"
>>> name_list = ["John Smith", "Bob Jones", "Bill Sanders", "Frank Smith"]
>>> for s in name_list:
...     if string.lower(name_to_remove) in string.lower(s):
...         del name_list[name_list.index(s)]
...         
>>> print name_list
['Bob Jones', 'Bill Sanders']

But don't import string to use these methods!!! This module has been deprecated (meaning DON'T USE THIS BECAUSE IT MAY NOT ALWAYS BE AVAILABLE). Instead, use the string itself as the object whose method you call:

name = "John Smith"
print name.lower()

Try something like this:

name_list = ["John Smith", "Bob Jones", "Bill Sanders"]
for i in range(len(name_list)):
    if "Smith" in name_list[i]:
           del name_list[i]
        break
print name_list
['Bob Jones', 'Bill Sanders']

or this:

for i in range(len(name_list)):
    if name_list[i].split()[1] == "Smith":
           del name_list[i]
        break

or this:

import string
name_to_remove = "SMITH"
for i in range(len(name_list)):
    if string.lower(name_list[i]).endswith(string.lower(name_to_remove)):
        del name_list[i]
        break

>>> print name_list
['Bob Jones', 'Bill Sanders']

I got the message Barton. My Python Essential Reference is based on 1.5.2, and my applications execute in 2.3, so I may be out of date. I'll try to keep up.

hi

thanks for the answers but what I'm trying do do is that I have a file with the first name, last name, birth day, adress and phonenumber written on seperate lines. Then I have read the information into a list. and then I want user to be able to type in the last name of the person they want to delete and then the person with all the information about birth day, adress and phone number should also be deleted from the list and from the file.

This is how the whole program looks like.
How can I make the method Remove work. It only says the name dosen't exist. I have tried to make this work for a long time now. Please help me.

 class Person:
    def __init__(self, firstname, lastname, birthday, adress):
        self.firstname = firstname
        self.lastname = lastname
        self.birthday = birthday
        self.adress = adress
 
 
 
class Register:
    def readFromFile(self):
        global name_list
        name_list = list()
        name_file = open("names.txt", "r")
        line = name_file.readline()
        while line != "":
            firstname = name_file.readline()
            lastname = name_file.readline()
            birthday = name_file.readline()
            adress = name_file.readline()
            name_list.append(Person(firstname, lastname, birthday, adress))
            line = name_file.readline()
        name_file.close()
 
 
    def Remove(self):
        name = raw_input("Enter the last name of the person you want to delete ")
        for i in name_list:
            if name == i.lastname:
                name_list.remove(i)
                print "Removed", i.firstname, i.lastname
                return
            else:
                print "The name doesn't exist."

That helps a lot! Here is something to get you started:

class Person:
    def __init__(self, firstname, lastname, birthday, adress):
        self.firstname = firstname
        self.lastname = lastname
        self.birthday = birthday
        self.adress = adress
 
 
 
class Register:
    def readFromFile(self):
        global name_list
        name_list = list()
        name_file = open("names.txt", "r")
        line = name_file.readline()
        while line != "":
            firstname = name_file.readline()
            lastname = name_file.readline()
            birthday = name_file.readline()
            adress = name_file.readline()
            name_list.append(Person(firstname, lastname, birthday, adress))
            line = name_file.readline()
        name_file.close()
 
 
    def Remove(self):
        name = raw_input("Enter the last name of the person you want to delete ")
        for person in name_list:
            if name == person.lastname:
                name_list.remove(person)
                print "Removed", person.firstname, person.lastname
                return
        else:
            print "The name doesn't exist."
 
 
if __name__ == "__main__":  # standard way to test a module
    name_list = []
    p = Person('joe', 'blow', 'june 12 1972', '1234 anywhere')
    name_list.append(p)
    p = Person('john', 'doe', 'june 12 1972', '1234 anywhere')
    name_list.append(p)
 
    print name_list
 
    reg = Register()
    reg.Remove()
 
    print name_list

Sorry, BV. I missed this post and have been aiming my posts at getting your attention.
