问题 This question already has answers here : Styling multi-line conditions in 'if' statements? [closed] (30 answers) Closed 7 years ago . When indenting long if conditions, you usually do something like this (actually, PyDev indents like that): if (collResv.repeatability is None or collResv.somethingElse): collResv.rejected = True collResv.rejectCompletely() However, this puts the block started by the if statement on the same indentation level as the last part of the if condition which makes it

问题 I am building a HTTP server for my android device. I am using a lot of IF-ELSE statements to handle differnt requests. As I will be sharing my code with other people for later use, I will have to make it as legible as possible. Right now, I can't even read my code with ease. I think the problem comes from using a lot of IF-ELSE statements in one class. For example. if(purpose.equals("readProfile"){ ..... } else if(purpose.equals("writeProfile"){ ..... } .... I tried classifying them in

问题 The following code provides two approaches that generate pairs of integers whose sum is less than 100, and they're arranged in descending order based on their distance from (0,0). //approach 1 private static IEnumerable<Tuple<int,int>> ProduceIndices3() { var storage = new List<Tuple<int, int>>(); for (int x = 0; x < 100; x++) { for (int y = 0; y < 100; y++) { if (x + y < 100) storage.Add(Tuple.Create(x, y)); } } storage.Sort((p1,p2) => (p2.Item1 * p2.Item1 + p2.Item2 * p2.Item2).CompareTo(

问题 The code works fine in detecting overlapping dates to not save a Booking if it already exist for a given Room. However, I had to twist my code to make it work because validation would make the update in my controller not valid instead of the save . So I want to know what is wrong with my code as normally the not valid should apply to the save and not the update. In fact, to tell me that a booking cannot be saved instead of throwing an error, it just did not update the booking.end_date in my

问题 I would like to extract items from a column in a data frame based on criteria pertaining to values in other columns. These criteria are given in the form of a list associating column names with values . The ultimate goal is to use those items to select columns by name in another data structure. Here is an example data frame: > experimental_plan lib genotype treatment replicate 1 A WT normal 1 2 B WT hot 1 3 C mut normal 1 4 D mut hot 1 5 E WT normal 2 6 F WT hot 2 7 G mut normal 2 8 H mut hot
