WEBVTT 00:00.080 --> 00:04.970 So you have seen how to respond to some comments that you send from the telegram. 00:04.970 --> 00:06.380 Chat with the bot. 00:06.410 --> 00:11.300 But now what if you just want to send a message to that group, for example? 00:11.720 --> 00:15.410 Because here we can send a message to the group when we have a callback function. 00:15.410 --> 00:20.720 So basically when we first receive a message from the group, so you need to send something from the 00:20.720 --> 00:24.590 group, get that in the Python program and send a message back. 00:24.620 --> 00:31.220 Now, what if you just want to send a message without waiting for any input from the application? 00:31.220 --> 00:33.470 Well, that's what I'm going to show you now. 00:33.710 --> 00:35.690 I'm going to create a new program. 00:37.350 --> 00:41.180 You and, well, let's just take what we need from here. 00:41.190 --> 00:43.080 So the interpreter. 00:44.510 --> 00:50.180 We are going to need also this to get the token. 00:52.300 --> 00:52.840 Okay. 00:52.840 --> 00:53.710 And now? 00:53.710 --> 00:57.660 Well, we are not going to need the updater or the command handler. 00:57.670 --> 01:04.770 We are going to simply do from telegram import bot. 01:05.600 --> 01:05.700 Okay. 01:05.950 --> 01:17.020 And we are going to create a bot is equal to bot with token is equal to telegram token. 01:17.710 --> 01:28.210 And then from that bot we can just do bot dot send message and here like we did before, we need to. 01:28.240 --> 01:30.540 So that's the same function here. 01:30.550 --> 01:33.460 We need to give the chat ID and the text. 01:33.820 --> 01:39.930 So chat ID is equal to well what is the chat ID of this group? 01:39.940 --> 01:41.200 How to know that. 01:41.320 --> 01:49.000 So you could go on internet and there are some methods to find the chat ID for this specific chat. 01:49.000 --> 01:55.640 But now that we have already a program that can receive command from the chat, what we can do is just 01:55.640 --> 02:00.920 use this program to get the chat ID and then use the chat ID in this other program. 02:01.460 --> 02:03.620 Okay, let me show you how to do that. 02:03.620 --> 02:11.210 So in the start handler that's a good place because we receive some context and some update from the 02:11.210 --> 02:11.870 chat. 02:12.050 --> 02:18.470 And as you can see here, we respond by using update dot effective chat.id. 02:18.470 --> 02:25.460 So basically effective chat is the chat you are using here to send the start command here and then the 02:25.490 --> 02:26.930 ID is the ID of this. 02:26.930 --> 02:29.720 So I'm just going to select this. 02:29.960 --> 02:36.800 I'm going to do here print update, dot effective chatted. 02:37.370 --> 02:38.990 I'm going to run that. 02:40.990 --> 02:41.920 So telegram bot. 02:41.920 --> 02:43.720 Ready and send. 02:44.140 --> 02:44.710 Start. 02:46.660 --> 02:48.400 Okay, you can see hello from Python. 02:48.400 --> 02:57.010 And we also have here the chat ID So for a group, usually you will have something that starts with 02:57.340 --> 02:57.910 a dash. 02:57.910 --> 02:58.240 Okay. 02:58.240 --> 03:04.780 So minus sign with the chat id so you can just copy this. 03:05.870 --> 03:08.030 And then go in the other program. 03:08.390 --> 03:11.150 Let's create a variable here. 03:11.390 --> 03:17.090 Chat ID is equal to this, so we keep it here. 03:17.540 --> 03:20.200 Actually, we don't just keep it as an integer. 03:20.210 --> 03:21.070 This is a string. 03:21.080 --> 03:21.310 Okay? 03:21.320 --> 03:28.310 So we make sure this is as a string and then chat ID is equal to chat ID, so no problem with this. 03:28.310 --> 03:33.200 This is the name of the parameter and this is the argument that we give. 03:33.530 --> 03:40.250 So we give the chat ID and then text is equal to let's use something different. 03:40.280 --> 03:41.690 Let's send some French. 03:41.690 --> 03:42.320 Bonjour. 03:44.150 --> 03:46.160 And let's just add a print here. 03:46.190 --> 03:46.730 Okay? 03:46.730 --> 03:49.490 So we can know from the Python program that we have sent something. 03:49.490 --> 03:52.580 So send message to chat. 03:54.080 --> 03:57.080 Let's run this and let's look at the chat here. 03:57.710 --> 04:00.350 Run script, let's name it. 04:00.380 --> 04:02.420 Send notification. 04:05.880 --> 04:06.120 Okay. 04:06.150 --> 04:08.880 Send message to chat and you can see bonjour. 04:08.880 --> 04:12.600 And we also have the notification here for the desktop application. 04:12.600 --> 04:17.250 If you are using your phone, you should also receive a notification. 04:17.250 --> 04:21.150 I just received a notification on my phone for this chat. 04:21.360 --> 04:21.630 Okay. 04:21.630 --> 04:26.970 If you don't have the notification on your phone, make sure you have correctly allowed notification 04:26.970 --> 04:30.210 for Telegram, but this is specific to your phone. 04:30.240 --> 04:30.480 Okay. 04:30.480 --> 04:39.330 Now you can see we can both respond to comments that we send from the chat and we can also send independent 04:39.330 --> 04:44.100 messages directly to the chat from a Python program.
