问题 Developing a very simple UPDATE query page for users to change their account password, but have run into a bit of a brick wall with establishing the MySQLi connection (or so it would seem). I'm new to this line of programming and this is my first attempt to perform a dynamic query, so hopefully it's something that one of you can spot easily enough and you'd so kind as to offer some much-needed sage advice. Here's the page in question: http://www.parochialathleticleague.org/accounts.html Upon

问题 On Windows, how can I add a Python version to the Python Launcher? I have python 3.7 installed alongside 2.7. I've made sure that the PATH variable and the registry keys are correct. One thing I will say is that I can't see any other Python environment variables on my machine (such as PYTHONPATH ), or either of the py.ini files descibed here. If possible, I would like the solution to also work with python distribition, such as Anaconda. This is the same question as py launcher does not find

问题 What happens if I use SHGetFolderPath api call in a 32 bit system with CSIDL_PROGRAM_FILESx86 folder id instead of the CSIDL_PROGRAM_FILES id? Theoretically CSIDL_PROGRAM_FILESx86 should map to C:\program files (x86) in a 64 bit system but what does it map to in a 32 bit system where this path doesn't exist? 回答1: The different scenarios are described in this article on MSDN. Scroll down to remarks, "FOLDERID_ProgramFiles" OS Application KNOWNFOLDERID Default Path CSIDL Equivalent 32 bit 32

问题 I am using jboss, eclipse and svn together. I have to files in my test folder: test/create.jsp and test/data.txt . What I want to do is when I call my create.jsp it will update my data.txt . Obviously I want my data.txt to stay where it is as other scripts are tryong to read from it. I have tried dozens of new ways to put the path to my File object but for some reason it creates the file under jboss war folders. Tried: ServletContext app = getServletContext(); String path1 = app.getRealPath("

问题 Problem Imagine you are writing a Python script which runs on cygwin and calls an external C# executable which requires as input a path. Assume you cannot change the C# executable in any way. As you send the path you want to the executable, it rejects all cygwin paths. So if you pass the path /cygdrive/c/location/of/file.html as a POSIX path, it will fail as the executable requires a Windows path like C:\location\of\file.html Example: Message location = os.path.dirname(os.path.realpath(__file

问题 Say I have the path gui/site/junior/profile.py How do I get this?: gui gui/site gui/site/junior Bonus if you tell me how to loop through each path :D 回答1: You can loop with awk: awk 'BEGIN{FS=OFS="/"} { for (i=1; i<=NF; i++) { for (j=1; j<i; j++) printf "%s/", $j printf "%s\n", $i } }' <<< "gui/site/junior/profile.py" See as one liner: $ awk 'BEGIN{FS=OFS="/"}{for (i=1; i<=NF; i++) { for (j=1; j<i; j++) printf "%s%s", $j, OFS; printf "%s\n", $i}}' <<< "gui/site/junior/profile.py" gui gui/site

问题 This question already has answers here : Get current page programmatically (4 answers) Closed 3 years ago . I need something that will uniquely identify my JSF (XHTML) page. I know that I have: String URI = servletRequest.getRequestURI(); This gives my full path, but that doesn't help if I use PrettyFaces or any other URL changing library. 回答1: You can use UIViewRoot#getViewId() for this: String viewId = FacesContext.getCurrentInstance().getViewRoot().getViewId(); It's also available in EL as

问题 When I try to make tensorboard, Syntax error comes out. I can not understand in spite of open source code. I tried to search about code for tensorboard but It's unclear. Even I'm not good at python. I write the path in this way, C:\\Users\\jh902\\Documents\\.logs because I'm using Windows 10 but I'm not sure. (I used double back slash but in this monitor it seems like one slash). If I code like this, tensorboard --logdir="C:\Users\\jh902\\Documents\\.logs" this error message comes out File "

问题 I am writing a Python code using pandas that will open a .csv file and read some parameters that will be used later as input for another module. Along the parameters the code must read, there are locations (paths) of other .csv files in my internal network that contain data that must be incorporated later on to the final output. My problem is opening those files; unless I define explicitly the path (instead of using a reference variable that will allow me to loop over all the .csv files my

问题 from bar import foo allows one to import function foo from module bar, without importing the whole module. Now, this thread: Python 3.4: How to import a module given the full path? shows different methods to import a module given it's full path depending on python's version. Is their a way to import function foo from module bar given the absolute path of bar and without importing whole module bar ? Thanks in advance for any tips 回答1: No, there is no such way. That said... from bar import foo
