C# preprocessor differentiate between operating systems

Using absolute unix paths in windows with python
Use os.path.abspath(), and also os.path.expanduser() for files relative to the user’s home directory: print os.path.abspath(“/var/lib/blob_files/myfile.blob”) >>> C:\var\lib\blob_files\myfile.blob print os.path.abspath(os.path.expanduser(“~/blob_files/myfile.blob”)) >>> C:\Users\jerry\blob_files\myfile.blob These will “do the right thing” for both Windows and POSIX paths. expanduser() won’t change the path if it doesn’t have a ~ in it, so you can safely use it with all paths. … Read more

How can I move file into Recycle Bin / trash on different platforms using PyQt4?
