input

问题 import sys s1 = input() s2 = sys.stdin.read(1) #type "s" for example s1 == "s" #False s2 == "s" #True Why? How can I make input() to work properly? I tried to encode/decode s1 , but it doesn't work. Thank you. 回答1: If you're on Windows, you'll notice that the result of input() when you type an 's' and Enter is "s\r" . Strip all trailing whitespace from the result and you'll be fine. 回答2: You didn't say which version of Python you are using, so I'm going to guess you were using Python 3.2

问题 I Recently Noticed in Google Chrome it is showing blue color background for all inputs elements which are auto filled values 回答1: Yes Google changed the background color of the autofill preview to GoogleBlue50 . You can find the issue here: https://bugs.chromium.org/p/chromium/issues/detail?id=935991 Since Google Chrome 72 the new autofill color is #E8F0FE / rgb(232, 240, 254) . Until Google Chrome 72 the autofill fields were colored with #FAFFBD / rgb(250, 255, 189) : input { border: 1px

问题 I'm dealing with some Java code in which there's an InputStream that I read one time and then I need to read it once again in the same method. The problem is that I need to reset it's position to the start in order to read it twice. I've found a hack-ish solution to the problem: is.mark(Integer.MAX_VALUE); //Read the InputStream is fully // { ... } try { is.reset(); } catch (IOException e) { e.printStackTrace(); } Does this solution lead to some unespected behaviours? Or it will work in it's

问题 I was trying to do like the following: a = input('Enter your name:_____________________________________________') but here, the cursor is positioned at : Enter your name:_____________________________________________ ^ Here How do I position the cursor at: Enter your name:_____________________________________________ ^ Here I'm doing this on IDLE. (Command prompt is also appreciated :) ) 回答1: Having looked at this further, my final solution is to create my own custom input. NB: this only works

问题 I've done a bunch of googling, but I can't find an answer anywhere that works for me. I'm creating a form (for the first time ever) and I need a red asterisk directly next to the placeholder text in the input boxes. Embarrassingly, this is the closest I have been able to get so far: form { margin: 0 auto; background-color: #3d549a; } input { font-family: avenir; font-size: 17px; color: #ffffff; font-weight: 100; border: none; width: 400px; padding: 15px; border-radius: 5px; } textarea {

问题 I'm trying to get unity to recognize that I am swiping left to right, I have solved that but my issue is that it doesn't understand this till I lift my finger off the screen.

问题 Can anyone check this code and let me know what is wrong? input_list = ["One", "Two", "Three"] P1 = input("Select the input: ", input_list[0], input_list[1], input_list[2]) print (P1) 回答1: With python's raw_input it is not possible to give a preselected list to the user to choose from. With raw_input we collect raw strings. update : a nice solution is to use the new pick library: https://github.com/wong2/pick It provides a small curses interface to pick our choice from a given list. Get it

问题 I am developing an OS X application that is supposed to take input from two mice. I want to read the motion of each mouse independently. What would be the best way to do this? If that is not possible, is there a way to disable/enable either of the mice programmatically? 回答1: The HID Class Device Interface is definitely what you need. There are basically two steps: First you need to find the mouse devices. To do this you need to construct a matching dictionary and then search the IO Registry
