I'm having hard time trying to read my dictionary variable. Python keeps throwing the following error:

TypeError: string indices must be integers

This is a sample that should give you an idea of what my problem is:

self.dict = {}
self.dict['User'] = 'User_name'
self.dict['Dir'] = 'user_home_dir'
self.dict['userID'] = 1if self.dict['userID'] == 1:    # this is the line that is said to contain an errorthen do somethin ...

This is all I get as a Traceback:

user_id = self.dict['userID']
TypeError: string indices must be integers

No I'm positive that self.dict is not a string.

It's being created in a function called createUser and it's being returned to the main thread.

def createUser(self):self.dict = {}... user inputs information ...... and then information is inserted into self.dict ...self.dict['User'] = self.lineEdit_User.text()self.dict['Dir'] = self.lineEdit_path.text()self.dict['userID'] = int(self.lineEdit_ID.text())return self.dict

After that self.dict is only referenced for reading data from it.

I've found the problem, and it was in my signal definition. Dictionary 'self.dict' is being returned via pyqtSignal which was defined like this:

addUser = pyqtSignal(object)

After thorough examination of my code I've figured out that I should change it to:

addUser = pyqtSignal(dict)

and once I did that it was all right. Once again, thanks everyone for their contribution.
