merge

问题 HI This is a follow up from one of my previous questions how do I perform a vlookup equivalent operation on my dataframe with some additional conditions As in the other question, my first dataframe is list = ['Computer', 'AA', 'Monitor', 'BB', 'Printer1', 'BB', 'Desk', 'AA', 'Printer2', 'DD', 'Desk', 'BB'] list2 = [1500, 232, 300, 2323, 150, 2323, 250, 2323, 23, 34, 45, 56] df = pd.DataFrame(list,columns=['product']) df['number'] = list2 and what if my 2nd dataframe has multiple values for

问题 Exist a faster way to merge two deques than this? # a, b are two deques. The maximum length # of a is greater than the current length # of a plus the current length of b while len(b): a.append(b.popleft()) Note that I'm not interested in preserving input deques, I'm only interested in having the merged one as fast as possible. 回答1: There's no need for elementwise appending, you can just use += : from collections import deque a = deque([1, 2, 3]) b = deque([4, 5, 6]) a += b print(a) deque([1,

问题 I made a branch ( folders ) that was deliberately experimental, did stuff on it, eventually liked it, rebased interactively to reduce the number of commits, and rebased or cherry-picked into master . I deleted the branch-name and waited for the commits on that "branch" to die of their own accord. But then for some reason the nameless "branch" got itself merged into master . I have no idea how that happened; I think it had something to do with pushing and pulling. So now I've got these two

问题 I frequently use the msdb.dbo.sp_send_dbmail tool in SQL Server for automated reports and such but I've never really used it to for an update/delete type statement in the @query section. Is it possible to do so? When I run this query, it gives 0 results and doesn't execute the actual Merge and Delete function within the @query section. I'm running a test scenario where I know there should be results, and that it should be deleted but no dice. Any advice appreciated as I may be missing

问题 I'm trying to use jq to parse a NOAA data feed into just the values I need: http://forecast.weather.gov/MapClick.php?FcstType=json&lat=39.56&lon=-104.85 I'm able to (separately) extract the two arrays I'm looking to combine: $ cat noaa.json | jq .time.startPeriodName [ "Today", "Tonight", "Friday", "Friday Night", "Saturday", "Saturday Night", "Sunday", "Sunday Night", "Monday", "Monday Night", "Tuesday", "Tuesday Night", "Wednesday" ] $ cat noaa.json | jq .data.weather [ "Mostly Sunny",

问题 I am trying to solve a question wherein overlapping intervals need to be merged: https://leetcode.com/problems/merge-intervals/description/ The question is: Given a collection of intervals, merge all overlapping intervals. For example, Given [1,3],[2,6],[8,10],[15,18], return [1,6],[8,10],[15,18]. I tried my solution: # Definition for an interval. # class Interval: # def __init__(self, s=0, e=0): # self.start = s # self.end = e class Solution: def merge(self, intervals): """ :type intervals:

问题 var Arr1 = [1,3,4,5,6]; var Arr2 = [4,5,6,8,9,10]; I am trying to do merge these two arrays and output coming is [1,3,4,5,6,4,5,6] I have used $.merge(Arr1, Arr2); this piece to merge them. Using alert I can see the merged array like above. Now my question is how can I get the following output: [1,3,4,5,6,8,9,10] i.e. the elements should be unique as well as sorted in the same manner I have mentioned. Please help. 回答1: You can use Array.prototype.sort() to do a real numeric sort and use Array
