问题 I have a following mongoDBschema- ObjectIDs are multiple entries in the database ,in which the further data is stored. ObjectId("a") posts [0] comments [0] comment fb_id [1] [2] [3] [4] ObjectId("b") ObjectId("c") I am trying to cumulatively add the sentiment value,I am assigning to the dictionary for each comment corresponding to every fb_id.I tried using counter method but it's values are emptying before entering another id's comment automatically. Earlier,I asked this question-Cumulatively

How to show Dropwizard active requests in logs

由 江枫思渺然 提交于 2020-01-16 13:19:08
问题 This question is related to the one I ask here. I'm trying to log the number of active requests being made to my Dropwizard application every 10 minutes. The idea is to track usage of the app so it can get the proper support. In doing this, I'm trying to expose the dropwizard metrics to the logs. For testing purposes, I've made the following code: @GET @Path("/metrics") public MetricRegistry provideMetrics() { MetricRegistry metrics = new MetricRegistry(); metrics.register("io.dropwizard

jquery counter/uncounter function

由 ε祈祈猫儿з 提交于 2020-01-15 18:18:33
问题 I'm working on a function where users can click a star and a counter will increase and the word Unlike will appear. Then, if users click on Unlike the counter decreases and the word Unlike disappears. So far, it works. The challenge is this: I want each user to only be able to click once (that's working now) but I want them to be able to click the star again IF they have already clicked the Unlike phrase (which would have removed the number from the counter). (Code and jsfiddle below). HTML

Adding a single character to add keys in Counter

由 假装没事ソ 提交于 2020-01-15 07:40:29
问题 If the type of a Counter object's keys is str , i.e.: I could do this: >>> vocab_counter = Counter("the lazy fox jumps over the brown dog".split()) >>> vocab_counter = Counter({k+u"\uE000":v for k,v in vocab_counter.items()}) >>> vocab_counter Counter({'brown\ue000': 1, 'dog\ue000': 1, 'fox\ue000': 1, 'jumps\ue000': 1, 'lazy\ue000': 1, 'over\ue000': 1, 'the\ue000': 2}) What would be a quick and/or pythonic way to add a character to all keys? Is the above method the only way to achieve the

Intersection of two Counters

由 て烟熏妆下的殇ゞ 提交于 2020-01-13 08:52:48
问题 I'm trying to find the shared elements (and the shared number of occurrences) between two lists. For example, the intersection of these two lists: a = [1, 1, 2, 3, 4, 5, 6, 7, 8, 1] b = [1, 1, 3, 5, 7, 9] should return Counter({1: 2, 3: 1, 5: 1, 7: 1}) or something similar, e.g. {1: 2, 3: 1, 5: 1, 7: 1} or [1, 1, 3, 5, 7] (order of the list doesn't matter). I already have an approach that works: cnts_a = Counter(a) cnts_b = Counter(b) cnts_a_b = Counter() # counter for the shared values for
