Solve the following python programming problem given the following code:
def poll(self) : 
    'Scans the mailbox for new messages

        Returns
        =======
        A string representing the current mailbox state
        ' 
    state = { 
        
} 
    def to_maildir_fmt(paths) : 
        for path in iter (paths) : 
            (yield path.rsplit (':') [0]) 
for subFolder in self.subFolders : 
        path = os.path.join (self.maildirPath, subFolder ['path']) 
        maildir = mailbox.Maildir (path) 
        state [subFolder ['label']] = 0 
        for file in to_maildir_fmt (os.listdir (os.path.join (path, 'new'))) : 
            if (state in maildir) : 
                state [subFolder ['label']] += 1 
return self.format_text (state)
