问题 print "How old are you?", age = raw_input() print "How tall are you in inches?", height = raw_input() print "How much do you weigh in pounds", weight = raw_input() print "So, you are %r years old, %r inches tall, and %d kilograms." % ( age, height, weight / 2.2) So I am new to code and this is my code. When I use terminal to compile it, I get this: How old are you? 1 How tall are you in inches? 1 How much do you weigh in pounds 1 Traceback (most recent call last): File "ex11.py", line 9, in

问题 I have an existing python script and I want to wrap it in a GUI. Since I already have tkinter installed I would like to use it if possible. At the moment my script has many places where it asks for user input using raw_input(). I would like to replace these with either a modal pop-up asking for user input or (preferably) an Entry object which responds to the enter key. 回答1: UI toolkits usually have an event-driven model where the main loop is in the toolkit itself. This is probably different

问题 I need to set up user permissions within the same table, based on the value of a field. I know that this is not directly possible in Access but a post on Allenbrown.com points to a way of doing this see here. I'm not proficient in coding so I'm hoping that I can get some directions from you. Here are the details: I have two tables in the database, a parent one populated via a form and a children one populated via a subform. The parent contains companies and the child contain subsidiaries of

问题 I'm pretty new to python and I wrote a simple blackjack card counting app. The app runs and after the user input it ends, I want it to continue asking for the user input and printing the count out. I don't want it to restart, I want it to continue. Ive included the source code. Thanks guys. count = 0 var = int(raw_input("Enter the value of the card: ")) if var == 1 : print count + 1 elif var == 2 : print count + 1 elif var == 3 : print count + 1 elif var == 4 : print count + 1 elif var == 5 :

Why white-spaces are not allowed in User Names as spaces are very natural to names and most of the computing

问题 I am working on a program that take user input for two file names. Unfortunately, the program can easily break if the user does not follow the specified format of the input. I want to write code that improves its resiliency against these types of errors. You'll understand when you see my code: # Ask the user for the filename of the qseq file and barcode.txt file print "Please enter the name of the qseq file and the barcode file separated by a comma:"; # user should enter filenames like this:

问题 How can I enter an input without causing the code to stop executing? I have been searching for an answer during the last 20 minutes without result. cin >> string; pauses the code AFAIK. Would I need to use mulithreading, or is there a better way? (I don't even know if multithreading would work.) I've recently started learning c++, I am a beginner to say the least, so please explain thoroughly and include any library I might need, thank you. 回答1: There are two algorithms for getting input
