Adress book
 

Hi attempting to make an address book program but hit a snag-
I have:
A class to give various attributes(phone numbers etc)to an instance
which then puts it all into a doc string which can be added to a dictionary-
but I want a function that will ask the user for the relevant information and then feed it to the class as the relevant arguments. however I Can't figure that out. Any Ideas-Section of code below:

class Data:

    def __init__(self, home, mobile, email):

        self.home = home

        self.mobile = mobile

        self.email = email

    def Coll_Data(self):

        self.info = """

Home Phone: %s

Mobile Phone: %s

Email: %s

""" % (self.home, self.mobile, self.email)



#the bit that doesn't work that needs changing is below:



def add_new():

    name = raw_input("Enter name to be added: ")

    h = raw_input("Enter home phone: ")

    m = raw_input("Enter Mobile phone: ")

    e = raw_input("Enter Email address: ")

    name = Data(h, m, e)

Please help!!!!!!

Re: Adress book
 

Oh I see, you want the instance name be the name of the person. That will not be a good idea, because identifiers in Python don't allow spaces.

A dictionary, where the name is the key and the value is a ( home, mobile, email ) tuple or list will do much better. You could also make the class instance the value of your dictionary.

Re: Adress book
 

Thanks, but making the class instance the value of the dictionary does not work it just returns the location of the instance in hexadecimal notation.

I have rejigged the code:

class Data:

    def __init__(self):

        self.home = raw_input("Enter home: ")

        self.mobile = raw_input("Enter mobile: ")

        self.email = raw_input("Enter email :")

    def Coll_data(self):

        self.info = """

Home : %s

Mobile : %s

Email : %s

""" % (self.home, self.mobile, self.email)

I intend to add it to the dictionary using self.info as the value.
But I really need a function that will create a variable and asign it to class Data.

Re: Adress book
 

This works just fine:

# create a dictionary of class instance values



class Data(object):

    def __init__(self, home, mobile, email):

        self.home = home

        self.mobile = mobile

        self.email = email

        self.get_info()



    def get_info(self):

        sf = \

"""Home Phone: %s

Mobile Phone: %s

Email: %s

"""

        return sf % (self.home, self.mobile, self.email)





name_dic = {}



# first set of data

name = 'frank'

home = '123-456-7890'

mobile = '456-789-0123'

email = 'frank23@gmail.com'



name_dic[name] = Data(home, mobile, email)



# second set of data

name = 'bob'

home = '234-567-8901'

mobile = '567-690-1234'

email = 'bob.dork@hotmail.com'



name_dic[name] = Data(home, mobile, email)



# get bob's email

name = 'bob'

print( name_dic[name].email )



print('-'*30)



# get the info for all names added so far

for key in name_dic:

    print( "Name = %s" % key )

    print( name_dic[key].get_info() )



"""

my output -->

bob.dork@hotmail.com

------------------------------

Name = frank

Home Phone: 123-456-7890

Mobile Phone: 456-789-0123

Email: frank23@gmail.com



Name = bob

Home Phone: 234-567-8901

Mobile Phone: 567-690-1234

Email: bob.dork@hotmail.com

"""

Remember that the name string is the dictionary key and has to be unique.

Re: Adress book
 

Thanks
that was extremely helpful

Re: Adress book
 

Using the code you gave me, I modified it a bit to enable more easy user interaction, but I want a function to change an attribute of an entry, say the email.
heres the code so far

intro = "Welcome to Adress_Book.py"

name_dic = {}

loop = 1

menu_choice = 0



class Data(object):

    def __init__(self, home, mobile, email):

        self.home = home

        self.mobile = mobile

        self.email = email

        self.get_info()



    def get_info(self):

        sf = \

"""Home Phone: %s

Mobile Phone: %s

Email: %s

"""

        return sf % (self.home, self.mobile, self.email)



def add_new():

    name = raw_input("Enter name: ")

    home = raw_input("Enter home: ")

    mobile = raw_input("Enter mobile: ")

    email = raw_input("Enter email: ")



    name_dic[name] = Data(home, mobile, email)



def printout():

    for key in name_dic:

        print( "Name = %s" % key )

        print( name_dic[key].get_info() )



def look_up():

    search = raw_input("Enter name to be searched: ")

    if name_dic.has_key(search):

        print( "Name = %s" % search )

        print( name_dic[search].get_info() )



    else:

        print( "Name %s not found" % search )



def del_entry():

    d_search = raw_input("Enter name to be deleted: ")

    if name_dic.has_key(d_search):

        del name_dic[d_search]

        print( "Name %s deleted" % d_search)



    else:

        print( "Name %s not found" % d_search )



def change_att():

    c_search = raw_input("Enter name to alter: ")

    if name_dic.has_key(c_search):

        c_name = raw_input("What element do you want to change: ")

        if c_name == 'email':

            n_e = raw_input("Enter new email adress: ")

            #n_e being the new email adress

so how can I take n_e and swap it for the old email adress

I want to write file I/O for this, having tried before and failed, so could someone pls point me in the right direction.

Re: Adress book
 

cheers, but do you have any ideas on pickleing this to create file io
especially regarding the load

Re: Adress book
 

I have to say that from python 2.5 and on you can use the 'a' file open method (append), which just adds to the data already in the file, i changed all of my programs to use this instead and it works so much faster
