Setting PYTHONPATH from code
Hi! Can someone tell me how to set PYTHONPATH variable in code when working with Python.Runtime.dll without changing the value in the system variables before.

Hi Sharon, What do you want to achieve with this? If you want to provide path for loading your own modules you can change the sys.path value by e.g. running a 'initialization' script with import sys sys.path.insert(0, 'your/own/path') You can build up the script above in C# by inserting the path you need and then performing e.g. RunSimpleString(<script>) like string script = "import sys\nsys.path.insert(0, '" + <variable_with_path> + "')"); IntPtr pythonLock = AcquireLock(); RunSimpleString(script); ReleaseLock(pythonLock); Does this help? 2011/2/10 Sharon Rozenblum <Sharon.Rozenblum@sandisk.com>

Hi! Trying to do as you said: string script = "import sys\nsys.path.insert(0, '" + modulePath + "')"; IntPtr pythonLock = PythonEngine.AcquireLock(); PythonEngine.RunSimpleString(script); PythonEngine.ReleaseLock(pythonLock); And then: IntPtr gs = PythonEngine.AcquireLock(); pyportal = PythonEngine.ImportModule(moduleName); if (pyportal == null) { … } … I got Null value from the ImportModule.

Hi Sharon, I don't use Python.NET, but I use IronPython and this is a snippet I use to add PYTHONPATH to the sys.path object: I use system variables to do so (for various reasons) at the studio. import sys from System import Environment as sysEnv PythonPath = sysEnv.GetEnvironmentVariable('PYTHONPATH') sys.path.extend(PythonPath.split(';')) Hope this helps.

Hi! I need to run some python scripts at the same time where each one of them is in different location & their location is not in the machine environment variable.

This is the code I use all the time to append a dir to the system path and then load assemblies from that dir. (note, they’re not in the GAC {woot!}) if os.path.isfile(myFile): if not myDir in sys.path: sys.path.insert(0, myDir) clr.AddReference("myAssembly") myFile is the name of the assembly dll ala: “C:/testdir/myAssembly.dll” myDir would be: “C:/testdir” I always make sure that the namespace in the compiled assembly is the same as the filename. This seems to make things run more smoothly.

Hi! Tried after your mail. Does not change... Regarding the PYTHONPATH: I change it with code (System.Environment.SetEnvironmentVariable("PYTHONPATH",PathValue)) and it does not help me at the first run of the application. (I am getting Null value from the ImportModule) But, after closing the application & opening it again it works (event if changing the PYTHONPATH in the code) with the PYTHONPATH that was set in the run before...

Hi! Is there a way to show the console window when running Python from C# (in order to see the Python outputs, when the c# project is not console application) Thanks, SHARON From: Sharon Rozenblum Sent: Monday, February 28, 2011 7:19 PM To: 'oleksii.bidiuk@gmail.com'; 'Benjamin Aranguren' Cc: 'pythondotnet@python.org' Subject: RE: [Python.NET] Setting PYTHONPATH from code Hi! Checked again and found that I had in the end of the module path string the char:"\". After deleting it - it works for me as oleksii.bidiuk said: string script = "import sys\nsys.path.insert(0, '" + <variable_with_path> + "')"); IntPtr pythonLock = AcquireLock(); RunSimpleString(script); ReleaseLock(pythonLock); ( with the "\n" delimiter!) Thanks to all! SHARON From: Sharon Rozenblum Sent: Monday, February 28, 2011 3:49 PM To: 'Benjamin Aranguren' Cc: pythondotnet@python.org Subject: RE: [Python.NET] Setting PYTHONPATH from code Hi! Tried after your mail. Does not change... Regarding the PYTHONPATH: I change it with code (System.Environment.SetEnvironmentVariable("PYTHONPATH",PathValue)) and it does not help me at the first run of the application. (I am getting Null value from the ImportModule) But, after closing the application & opening it again it works (event if changing the PYTHONPATH in the code) with the PYTHONPATH that was set in the run before... Any Idea?

If you want to provide path for loading your own modules you can change the sys.path value by e.g. running a 'initialization' script with import sys sys.path.insert(0, 'your/own/path') You can build up the script above in C# by inserting the path you need and then performing e.g. RunSimpleString(<script>) like string script = "import sys\nsys.path.insert(0, '" + <variable_with_path> + "')"); IntPtr pythonLock = AcquireLock(); RunSimpleString(script); ReleaseLock(pythonLock); Does this help? 2011/2/10 Sharon Rozenblum <Sharon.Rozenblum@sandisk.com<mailto:Sharon.Rozenblum@sandisk.com>> Hi! Can someone tell me how to set PYTHONPATH variable in code when working with Python.Runtime.dll without changing the value in the system variables before.

Hi Sharon, I haven't found a way to run a console, but I had achieved a similar effect by redirecting the stdout and stderr from within Python (as suggested some time ago by Guido himself in a related embedded CPython post) to a .NET object and then show the incoming strings in a TextBlock (I am using a WPF app that hosts Python.NET). Below is a very short description of what I have done. Please let me know if this is indeed what you were looking for (or perhaps somebody else), I will prepare a more detailed post then (need to recap details from code). To achieve having 'live' console output I have used some 'setup script' and 'clean up' scripts executed before and after the user-defined script. In the setup script I first backup the curent value of sys.std* objects and then assign my own (.NET) object to sys.stdout and in the clean up part I restore the original std* values (similar to the sample for inserting certain path to the sys.path discussed before). To make use of the technique described above you need to have a .NET object that implements the same interface as python stream (meaning write, writelines, etc methods, see dir(sys.stdout) for all the details). In my experience write() and writelines() is enough. Having that you can pass an instance of such object to your Python code. As soon as you have the information coming through your .NET object methods you can do things like raising events, adding text to GUI, dump to a file, etc. It does require a bit of additional work, (which I honestly already expected to see already in Python.NET) and to some extend similar to the concept of console redirection per script context in IronPython, although in IronPython it is done in a 'native' .NET way. I am not sure this is THE best solution and other suggestions are more than welcome! 2011/3/1 Sharon Rozenblum <Sharon.Rozenblum@sandisk.com>

Hi Oleksii & Sharon, If you've done this before, would you share which I can get a console window in embedded Python.Net and get the Python string output from C#? Thank you, Spark. On Tue, Mar 1, 2011 at 1:33 PM, Oleksii Bidiuk <oleksii.bidiuk@gmail.com>wrote:
