i'm trying make basic window text "t" inside using tkinter, when running code shell spits out "nameerror: name 'label' not defined". i'm running python 3.5.2. i followed tutorials problem in label = label(root, text="test") line. import tkinter root = tkinter.tk() sheight = root.winfo_screenheight() swidth = root.winfo_screenwidth() root.minsize(width=swidth, height=sheight) root.maxsize(width=swidth, height=sheight) label = label(root, text="test") label1.pack() root = mainloop() is label function different in 3.5.2? you never imported label class. try tkinter.label check import statements tutorials maybe imply from tkinter import *

is possible read static tag id of epassport? each time try read tag id android device gives me random 1 (it's described here: https://randomoracle.wordpress.com/2012/09/07/nfc-in-us-passports-verifying-the-random-id/ ). i understand mrtd application inside card requires bac read personal information name, nationality, image etc, don't need data. i'm wondering, if it's possible stable card's id sure, it's same card i've read while ago. no not possible intention. see icao 9303, part 11 , chapter 4. attempt can't distinguished skimming, i. e. tracing, whether same passport here , @ time, without proof, card holder agreed (by presenting or card, terminal can read optical information necessary bac).

i have container class array list defined person object. the person using program asked register person , have create object person, give name, lastname , age user inputed , after add arraylist. my question is, when creating person object, can give same name every object add? or have name them person1, person2, etc? if so, how? thanks no, don't have give them different names. doing defeat purpose of using collection. can following: person p = new person(...); // set name, age, etc. list.add(p); each time that, new person created , added list. think of name p temporary variable can discarded.
