path

问题 I have a path which looks like /First/Second/Third/Fourth/Fifth and I would like to remove the First from it, thus obtaining Second/Third/Fourth/Fifth The only idea I could come up with is to use recursively os.path.split but this does not seem optimal. Is there a better solution? 回答1: There really is nothing in the os.path module to do this. Every so often, someone suggests creating a splitall function that returns a list (or iterator) of all of the components, but it never gained enough

问题 I just used brew to install Python 3 on OS X. The python3 command now starts the interpreter using brew Python 3.6, but python still opens the interpreter with the default system Python 2.7. My understanding was that, by default, brew Python should now override system Python. (I.e., see Order of /usr/bin and /usr/local/bin and more in $PATH). In my PATH, /usr/local/bin comes before /usr/bin, so it shouldn't be a PATH issue. I have tried restarting Terminal, with no effect. Here is my full

问题 I'm developing Django apps on my local windows machine then deploying to a hosted linux server. The format for paths is different between the two and manually replacing before deployment is consuming more time than it should. I could code based on a variable in my settings file and if statements but I was wondering if anyone had best practices for this scenario. 回答1: The Django book suggests using os.path.join (and to use slashes instead of backslashes on Windows): import os.path TEMPLATE

问题 When setting the export path in Unix, example: export PATH=$PATH: $EC2_HOME/bin If I quit terminal and open it back up to continue working, I have to go through all the steps again, setting up the paths each time. I'm wondering how I can set the path and have it "stick" so my system knows where to find everything the next time I open terminal without having to do it all over again. Thanks! 回答1: Open ~/.bashrc. This file is loaded every time you start up a new shell (if you're using Bash,

问题 Trying to install node.js. Did brew install node It seems to have worked. However, received this message upon its completion Homebrew installed npm. We recommend prepending the following path to your PATH environment variable to have npm-installed binaries picked up: /usr/local/share/npm/bin Ok ... so, I open my bash_profile ... And this is what I have in it: export PATH="/usr/local/bin:/usr/local/sbin:~/bin:$PATH" [[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load

问题 I used to think that everyone used relative paths (e.g. /styles/style.css ). But I wonder why some popuar web designers (e.g. http://www.getfinch.com and http://31three.com/) use absolute paths ( http://example.com/styles/style.css ). So basically I'm asking why some professional designers are using absolute paths instead of relative paths? 回答1: Both of those are using ExpressionEngine CMS, it's probably the way the CMS links the stylesheets. But really it's just a matter of preference.

问题 My app needs to install some files that can be edited by the application at run time. Install shield provides an alias [CommonAppDataFolder] that will resolve to c:\programData on Vista and Windows 7 and will also work on Windows XP. Is there a win32 function that will return a similar path? Maybe I need to call different functions depending on the operating system? 回答1: SHGetFolderPath/ SHGetSpecialFolderPath get you that, with CSIDL_COMMON_APPDATA argument. See code snippet here (at the

问题 I wish to add git to my PATH in Windows 7, through the "shell" command in R. shell('set PATH=%PATH%;"C:\\Program%20Files%20(x86)\\Git\\bin"', intern = TRUE) shell("echo %PATH% ", intern= TRUE) But I do not see that path added. If I run the above code in cmd.exe, it does add it to PATH. Any idea what is the issue? UPDATE: I ended up manually running the following through cmd.exe (which I made sure to run as admin) setx PATH "C:\\Program Files (x86)\\Git\\bin" Which worked. But I wish I could
