[ "Python Count Items in Dictionary", "I would like to count part of speech tags. So far I have the part of speech tags (for German) stored in a dictionary, where the key the POS-tag is, and the value the number of occurrences is. \n\nWhen I count, I want to summarize 'NN' and 'NE' as one variable 'nouns_in_text', because both of them are nouns. I did this partially successfully. When I have an input-text in which I have both 'NN' and 'NE', in this case my code is working, and I get the correct result, meaning the sum of 'NN' and 'NE'.\n\nBut the problem is, when I have an input text, which for example has only 'NN' and no 'NE', then I get a KeyError.\n\nI need the code to look if there are 'NN' or 'NE' in the input-text. If there are 'NN' and 'NE', then sum them up. If there is only 'NN' then return just the number of occurrences for 'NN', and the same if there is only 'NE'. In case there is neither 'NN' nor 'NE' return 0 or \"None\".\n\nI would like a Code, that would work for all three in the following described scenarios, without getting an Error.\n\n# First Scenario: NN and NE are in the Input-Text\nmyInput = {'NN': 3, 'NE': 1, 'ART': 1, 'KON': 1}\n\n# Second Scenario: Only NN is in the Input-Text\n#myInput = {'NN': 3, 'ART': 1, 'KON': 1}\n\n# Third Scenario: Neither NN nor NE are in the Input-Text\n#myInput = {'ART': 1, 'KON': 1}\n\ndef check_pos_tag(document):\n return document['NN'] + document['NE']\n\nnouns_in_text = check_pos_tag(myInput)\nprint(nouns_in_text)\n\n# Output = If NN and NE are in the input text I get 4 as result\n# But, if NN or NE are not in the input text I get a KeyError\n\n\nI think I could or should solve this problem with if-else conditions or with try-except blocks. But I'm not sure how to realize this ideas... Any suggestions? Thank you very much in advance! :-)" ]

But I'd like to save all push notifications as a listview. So each time a new push notification is received, the listview is rebuilt and updated with the latest push notification at the top. Ideally, the user should be able to scroll back and see all the push notifications they've ever received.\nIs this possible? Here's the code for displaying a single notification;\nimport 'package:flutter/material.dart';\nimport 'package:fcm_config/fcm_config.dart';\n\nFuture<void> _firebaseMessagingBackgroundHandler(\n RemoteMessage _notification) async {\n\n String title = _notification.data["title_key"];\n String body = _notification.data["body_key"];\n FCMConfig.displayNotification(title: title, body: body);\n}\n\nvoid main() async { FCMConfig.init(onBackgroundMessage: _firebaseMessagingBackgroundHandler).then((value) {\n FCMConfig.subscribeToTopic("test_fcm_topic");\n });\n\n runApp(MyHomePage());\n}\n\nclass MyHomePage extends StatefulWidget {\n MyHomePage({Key key}) : super(key: key);\n @override\n _MyHomePageState createState() => _MyHomePageState();\n}\n\nclass _MyHomePageState extends State<MyHomePage>\n with FCMNotificationMixin, FCMNotificationClickMixin {\n RemoteMessage _notification;\n final String serverToken ='myservertoken';\n\n @override\n void initState() {\n super.initState();\n }\n\n @override\n Widget build(BuildContext context) {\n return MaterialApp(\n home: Scaffold(\n body: Center(\n child: Column(\n mainAxisAlignment: MainAxisAlignment.center,\n children: <Widget>[\n ListTile(\n title: Text("title"),\n subtitle: Text(_notification?.notification?.title ?? ""),\n ),\n ListTile(\n title: Text("Body"),\n subtitle: Text(\n _notification?.notification?.body ?? "No notification"),\n ),\n if (_notification != null)\n ListTile(\n title: Text("data"),\n subtitle: Text(_notification?.data?.toString() ?? ""),\n )\n ],\n ),\n ),\n ),\n );\n }\n\n @override\n void onNotify(RemoteMessage notification) {\n _firebaseMessagingBackgroundHandler(notification);\n setState(() {\n _notification = notification;\n });\n }\n\n @override\n void onClick(RemoteMessage notification) {\n setState(() {\n _notification = notification;\n });\n print(\n "Notification clicked with title: ${notification.notification.title} && body: ${notification.notification.body}");\n }\n}" ]

Matplotlib provides several functions which apparently do the same thing. pcolormesh is recommended instead of pcolor but what is the difference (from a practical point of view as a data plotter) between imshow and pcolormesh? What are the pros/cons of using one over the other? In what scenarios would one or the other be a clear winner?" ]

[ "Setting position of JQuery dialog buttons causes buttonpane background color issue", "I have created a JQuery dialog in my web page, and in it I have set up a couple of buttons. I wanted to ensure that the \"Register Me\" button appeared in the left corner of the buttonpane, and that the \"Maybe Later\" button appeared in the right corner, so I put in some code to handle this. Here's the complete code of the .dialog() declaration:\n\n $(\"#register\").dialog({\n create : function(ev, ui) {\n $(this).parent().find('.ui-dialog-buttonpane').css('background-color', '#ffffff;');\n },\n appendTo: \"form\",\n autoOpen: false,\n show: { effect: \"fadeIn\" },\n hide: { effect: \"fadeOut\" },\n modal: true,\n draggable: false,\n minWidth: 750,\n minHeight: 400,\n resizable: false,\n dialogClass: \"no-close\",\n buttons:\n [\n {\n class: \"firstButton\",\n text: \"Register Me\",\n click: function () {\n $.ajax({\n url: \"/services/register.asmx\",\n timeout: 30000,\n type: \"POST\",\n data: $('#modalform').serialize(),\n dataType: 'json',\n error: function (XMLHttpRequest, textStatus, errorThrown) {\n alert(\"An error has occurred making the request: \" + errorThrown)\n },\n success: function (data) {\n $(this).dialog(\"close\");\n }\n })\n }\n },\n {\n class: \"lastButton\",\n text: \"Maybe Later\",\n click:function () {\n $(this).dialog(\"close\");\n }\n }\n ]\n });\n\n\nAs you can see from the button declarations, I added a class for each one that floats the button to the left or right as desired. This all works, and the buttons appear on the left and right corners of the dialog as I expected.\nThe problem is that as long as I don't try to position the buttons, they appear on a white background as part of the \"buttonpane\" of the dialog. The moment I set the positioning of the buttons though, the background of the underlying buttonpane goes transparent, so now the buttons appear to float below the dialog, like this:\n\n\n\nIf you look at the dialog code, you'll see that I tried to resolve this by intercepting the create event in the dialog declaration to override jquery styling:\n\n$(this).parent().find('.ui-dialog-buttonpane').css('background-color', '#ffffff;');\n\n\nThis, however, doesn't seem to work. So I decided to try to change it after creation of the dialog by adding this code:\n\n $('.ui-dialog-buttonpane').css('background-color', 'white');\n\n\nNo joy on this either. I've tried setting up code in my stylesheet to achieve this as well, using this:\n\n.ui-dialog-buttonpane {\n background-color:#ffffff !important;\n}\n\n\nIt also has no effect. Can anyone tell me what I'm missing here, because I'm out of ideas. Thanks!" ]
