问题 I have just started learning how to code in Python and would appreciate if anyone could give me a brief explanation/hint on how to convert raw code into function(s). Example machine learning code: # create model model = Sequential() model.add(Dense(neurons, input_dim=8, kernel_initializer='uniform', activation='linear', kernel_constraint=maxnorm(4))) model.add(Dropout(0.2)) model.add(Dense(1, kernel_initializer='uniform', activation='sigmoid')) # Compile model model.compile(loss='binary

问题 Does anyone know why Stroustrup's style is the placement of pointers as follows? Specifically, what Stroustrup has provided for guidance about this matter? int* p; vs int *p; because declaring multiple variables would require the asterisk next to each variable name. Which would result in: int* p, *x; vs int *p, *x; In K&R C book, they explain that the asterisk/pointer is used as a mnemonic to aid in understanding. I find it odd that the pointer/asterisk is tied to the type, vs the variable as

问题 In puppet, if define command is > 80 characters, how can I wrap into two line to do it? exec { 'create_domain': command => "some command exceed 80 character...........................................................how to do how to do?.......", } 回答1: It's sort of ugly, but if the last character in a string is a '\' followed by a newline, then the string is continued on the next line. My sample.pp manifest is below: class test { exec { 'create_domain': command => "/bin/echo

问题 Perhaps in the app I have a feature allowing users to send feedback using a form with some validation logic: name can be empty feedback message should be at least 5 characters Where would you put these validation logic, either in domain layer as business logic or in presentation layer as UI logic? These logic are applied for all applications (android, iOS, web). Please note that we already had server side validation. 回答1: I think many developers do that in Presentation layer, specifically in

问题 I need to convert a cell with a double to a precentage. I used a macro in excel and it says: Range("B5").Select Selection.Style = "Percent" When I do this in c#, it doesn't work: Excel.Range procentRange = xlWorksheet.get_Range("A1","A1"); procentRange.Style = "Percent"; Anybody knows how to do this? 回答1: I've found the anwser with help of JN Web Excel.Range procentRange = xlWorksheet.get_Range("A1","A1"); procentRange.NumberFormat = "###,##%"; So first you need a range, then set the decimals
