In this section you're going to learn how to build 2 00:00:06,690 --> 00:00:08,990 graphical user interfaces with Python. 3 00:00:09,250 --> 00:00:14,410 And specifically are we are going to use the Tkinter library for that. 4 00:00:14,430 --> 00:00:20,580 So in this section you're not going to build any real world program. I'll introduce you to the Tkinter library. 5 00:00:21,180 --> 00:00:27,350 And of course to build a graphical user interface a small program that can get you started with Tkinter. 6 00:00:27,950 --> 00:00:28,980 And then in the next section, 7 00:00:28,980 --> 00:00:35,130 so once we are done with this section, in the next section you're going to learn how to interact with 8 00:00:35,130 --> 00:00:37,350 databases with Python. 9 00:00:37,710 --> 00:00:45,840 So we'll be using Python as a wrapper of SQL code so that we can store data in a database, query data 10 00:00:46,020 --> 00:00:49,080 delete and so on and so forth. 11 00:00:49,080 --> 00:00:51,170 So that was the section after this one. 12 00:00:51,190 --> 00:00:57,630 And then in the third section after this two sections we are going to build a real world program and 13 00:00:57,630 --> 00:01:00,290 that the program is this one here. 14 00:01:00,330 --> 00:01:02,330 So I called it bookstore. 15 00:01:02,490 --> 00:01:08,880 And what this does is it allows you to store book information in a database. 16 00:01:08,940 --> 00:01:11,460 This is a graphical user interface. 17 00:01:12,150 --> 00:01:15,110 So this program is made in two parts. 18 00:01:15,240 --> 00:01:20,790 You have the graphical user interface which are this buttons here which are called widgets and this was built with Tkinter. 19 00:01:21,090 --> 00:01:28,760 And then you have the backhand which consists of code that communicates with 20 00:01:28,770 --> 00:01:29,790 the database. 21 00:01:29,790 --> 00:01:36,690 So for example if we press the view all bottom we are quering the database to load all the books for us. 22 00:01:37,920 --> 00:01:40,270 So we have the title. 23 00:01:40,290 --> 00:01:48,570 So if you press one of them you get the title here, the author and the year of the book and also the book identification 24 00:01:48,570 --> 00:01:53,010 number which is called ISPN. You can also search for an entry. 25 00:01:53,010 --> 00:01:59,370 So if you want to search for an author you'd write the author name in here and press search. 26 00:01:59,670 --> 00:02:07,140 And if you want to add an entry you would just type that in. 27 00:02:08,520 --> 00:02:12,170 And yes something like that. 28 00:02:12,620 --> 00:02:13,520 Add entry. 29 00:02:13,960 --> 00:02:18,440 And if load them again your entry should be here. 30 00:02:18,480 --> 00:02:22,730 So this is the program we're going to build two sections after this one. 31 00:02:22,890 --> 00:02:29,750 So let me close this one here and in the next lecture I'll introduce you to the Tkinter library. 32 00:02:30,000 --> 00:02:34,280 So we'll be building some simple interfaces with some widgets. 33 00:02:34,420 --> 00:02:35,390 See you in the next lecture. 3482
