问题 I've been trying to figure this out for almost the whole day, and after several attempts, I figured I'd see if anyone here might have some ideas. Any help is welcome. I have a pretty simple table of ID's and Name's and I would like to get the last ID value in the table. Although I don't get any compile errors or run-time errors, I'm getting the wrong value for ID. According to SQLiteManager (which can directly check the database) my max ID is 10, however, no matter what I do I simply get a

问题 I have a pandas DataFrame in the following format: a b c 0 0 1 2 1 3 4 5 2 6 7 8 3 9 10 11 4 12 13 14 5 15 16 17 I want to append a calculated row that performs some math based on a given items index value, e.g. adding a row that sums the values of all items with an index value < 2, with the new row having an index label of 'Red'. Ultimately, I am trying to add three rows that group the index values into categories: A row with the sum of item values where index value are < 2, labeled as 'Red'

问题 I have a csv file like this: Name,PhoneNumber,Adress I want to get input from the user and change the name. I can delete the whole row. name = input("Enter a name : ") fieldnames = ["name", "number", 'address'] with open('book.csv', 'r') as csvfile, open('outputfile.csv', 'w') as output: reader = csv.DictReader(csvfile, fieldnames=fieldnames) writer = csv.DictWriter(output, fieldnames=fieldnames) for row in reader: if not name == row['name']: writer.writerow({'name': row['name'], 'number':

问题 The code below would search through a row and its associated columns. For Row 7, if it is a "N" or "TR" and if all entries are blank below line 12,the code would hide the entire column. However, I still need help with some further help! If there is a "N" or "TR" in row 7. If there is something writen in any cell, (rather than leaving it alone), can I highlight its associated cell in row 7 in yellow? If ther eis a "Y" in row 7, If there is any empty cells, can I highlight its associated cell

问题 Problem solved, solution added at bottom of posting! I'd like to know how to "fill" a data frame by inserting rows in between existing rows (not appending to the end). My situation is following: I have a data set with about 1700 cases and 650 variables Certain variables have possible answer categories from 0 to 100 (question was: "How many percent..." -> people could fill in from 0 to 100) Now I want to show the distribution of one of those variables (let's call it var ) in a geom_area().

问题 I would like to append a new row of 5 input tags to the <td> element, which is a child of <tr class="unit"> , and which is a grandchild of <table id="myTable"> element. In my Javascript code, I was able to console-log the 5 input tags, but was not able to append them to the <td> element and to the rest of the parent elements. Is my code on the right track for solving this? Here's a link to the what I'm doing http://codepen.io/johnnyginbound/pen/xZxZNo?editors=101 function addRow(){ var

问题 I'm trying to implement a Cassandra trigger such that when there is an update or a delete on keyspace1.tableA, the trigger will add a row to keyspace1.tableB. The names of the columns in tableB are completely different than the columns in tableA. I'm working with Cassandra 2.1, no option to move to a more recent version. Looking at the InvertedIndex trigger example at https://github.com/apache/cassandra/blob/cassandra-2.1/examples/triggers/src/org/apache/cassandra/triggers/InvertedIndex.java

问题 I am using a GridPane (inside a ScrollPane) as a table with user entries. Each row incorporates a username (Label), an icon depicting its state (ImageView) and two buttons, the second of which is used to delete the user entry. The two images below depict the scroll pane before and after the user entry deletion UPDATE: Code sample below: The obvious issue is that the GridPane items do not get automatically re-arranged and the deleted line still occupies space. Do I have to provide a method to
