I've run into an issue when after I append my list to my dictionary, I get an unwanted [...] at the end of my list.

Here's my code:

class Account:



    accountInfo = {} #ex. ID : 5FE19C (hexadecimal ID's)



    def __init__(self):

        choice = raw_input("Would you like to login or signup?n")

        if choice.lower() == "login":

            self.login()



        elif choice.lower() == "signup":

            print "Great! Fill in the following."

            self.signup()



        else:

            self.__init__()



    def signup(self):



        accountID = '%010x' % random.randrange(16**10) # 10 digit hexadecimal ID generator

        personalInfo = 



        self.accountInfo[accountID] = personalInfo



        firstName = raw_input("First Name: ")

        lastName = raw_input("Last Name: ")

        email = raw_input("E-Mail: ")

        password = raw_input("Password: ")

        birthdate = raw_input("DOB (DD/MM/YYYY): ")

        alias = raw_input("Username/Alias: ")



        personalInfo.append(firstName)

        personalInfo.append(lastName)

        personalInfo.append(email)

        personalInfo.append(password)

        personalInfo.append(birthdate)

        personalInfo.append(alias)



        self.accountInfo[accountID].append(personalInfo)



        print self.accountInfo

And here is my output:

>>> {'a92ab2fcea': ['firstName', 'lastName', 'email', 'password', 'birthdate', 'alias', [...]]}

Just wondering why it appears and how to remove it.

Thanks!

To understand what exactly happened, you need to know about references.

>>> a = 

>>> test['a'] = a

>>> a.append(1)

>>> a.append(2)

>>> test['a'] 

[1, 2]

When you did the line self.accountInfo[accountID] = personalInfo
What it actually did was pass the reference of personalInfo to self.accountInfo[accountID]

Meaning modifying personalInfo will also reflect in self.accountInfo[accountID]

self.accountInfo[accountID] = personalInfo >> {'a92ab2fcea': }



personalInfo.append(firstName) >> {'a92ab2fcea': ['firstName']} # Note: Since personalInfo changed, so self.accountInfo[accountID] also changed.



personalInfo.append(lastName) >> {'a92ab2fcea': ['firstName','lastName']}



personalInfo.append(email) >> {'a92ab2fcea': ['firstName','lastName','email']}



personalInfo.append(password) >> {'a92ab2fcea': ['firstName','lastName','email','password']}



personalInfo.append(birthdate) >> {'a92ab2fcea': ['firstName','lastName','email','password','birthdate']}



personalInfo.append(alias) >> {'a92ab2fcea': ['firstName','lastName','email','password','birthdate','alias']}



self.accountInfo[accountID].append(personalInfo) >> {'a92ab2fcea': ['firstName', 'lastName', 'email', 'password', 'birthdate', 'alias', [...]]} # What you are doing is appending personalInfo to personalInfo

What I think you meant to do is:

1. remove self.accountInfo[accountID] = personalInfo
   


2. replace self.accountInfo[accountID].append(personalInfo) with self.accountInfo[accountID] = personalInfo
   

But if you understand the reference concept,

1. keep self.accountInfo[accountID] = personalInfo
   


2. remove self.accountInfo[accountID].append(personalInfo)
   Should also work!

But the latter way is discouraged as it is less readable.

I think you mean

self.accountInfo[accountID].append(personalInfo)

to be

self.accountInfo[accountID] = personalInfo

you also don't need the latter line earlier in the code.
