This means that the % formatting needs to be done inside the parenthesis: 1

问题 For simple debugging in a complex project is there a reason to use the python logger instead of print? What about other use-cases? Is there an accepted best use-case for each (especially when you're only looking for stdout)? I've always heard that this is a "best practice" but I haven't been able to figure out why. 回答1: The logging package has a lot of useful features: Easy to see where and when (even what line no.) a logging call is being made from. You can log to files, sockets, pretty much

问题 I have a system where the user can register students, subjects, and the student grade in each subject, together with the topic and the date. You can search a particular student grades in a particular subject by entering the code of the student, and by selecting the subject from a combobox. If you search it, those things are displayed in the jTable1. Then, I have a PRINT button. When the user clicks the Print button, the content that is being displayed in the jTable1, goes to a jTable2, the

问题 The application is for pulling information to fill out a form from a database or write to the database from this form. Right now I can do both of those with using netbeans and contacting my MySQL test server that I have up and running at the moment. The issue I am having is I need to print the information attained from the database in a form like manner rather than a table, in order to match the hand written forms we are currently using at the office. Is there a way to print the entire JFrame

问题 I currently have the code: fleechance = random.randrange(1,5) print fleechance if fleechance == 1 or 2: print "You failed to run away!" elif fleechance == 4 or 3: print "You got away safely!" fleechance is constantly printing as 3 or 4, but I continue to get the result "You failed to run away!" ,can anyone tell me why this is happening? 回答1: The expression fleechance == 1 or 2 is equivalent to (fleechance == 1) or (2) .
