问题 This question already has answers here : About catching ANY exception (8 answers) Closed 10 months ago . I tried making a function to check if an image is displayed on the screen using PyAutoGui and came up with this: def check_image_on_screen(image): try: pyautogui.locateCenterOnScreen(image) return True except: return False And it works fine, but PyCharm tells me I shouldn't leave except bare. What is the problem with leaving it like this? Is there a more appropriate way of creating the

问题 I am trying to write a C++ application, using C++ REST SDK lib, that will process JSON data produced by a C# application. A C# program can produce JSON in a "wrapped" or "bare" style. Using BodyStyle = WebMessageBodyStyle.Wrapped , C# produces JSON like the following: {"Echo":"{\"firstname\":\"an'",\"number\":21,\"secondname\":\"pn\"}"} Using BodyStyle = WebMessageBodyStyle.Bare , C# produces JSON like this: "{\"firstname\":\"an'",\"number\":21,\"secondname\":\"pn\"}" How can my program

How can I remove the working copy from a Mercurial clone?

问题 When cloning a repository with mercurial you can pass the -U/--noupdate flag to create a clone with no working copy. Can I remove the working copy if I forget to pass this flag at clone time? And if so, how? This is conceptually similar to this git question, but for mercurial. 回答1: I might be missing the nuances here. Some one can correct me. Documentation at Mercurial wiki says following about bare repositories: " Although this is a minor issue, Mercurial can obviously handle a bare

问题 I can do this without issue: const char* foo = "This is a bare-string"; What I want is to be able to do the same thing with an array: const int* bar = {1, 2, 3}; Obviously that code doesn't compile, but is there some kind of array equivalent to the bare-string? 回答1: You can't do this: const int* bar = {1, 2, 3}; But you can do this: const int bar[] = {1, 2, 3}; Reason is that char* in C (or C++) have an added functionality, besides working as a char pointer, it also works as a "C string",

Is there any legitimate use for bare strings in PHP?

由 江枫思渺然 提交于 2019-11-26 17:19:43
问题 This question got me thinking about bare strings. When PHP sees a string that's not enclosed in quotes, it first checks to see if it's a constant. If not, it just assumes it's a string and goes on anyway. So for example if I have echo $foo[bar]; If there's a constant called bar it uses that for the array key, but if not then it treats bar as a bare string, so it behaves just like echo $foo["bar"]; This can cause all kinds of problems if at some future date a constant is added with the same
