LabView allows you to write extensions in several languages, the primary technique these days is to use a network connection. Native language toolkits that run inside the labview process itself are avoided.

It seems there is a Python <a href="http://labpython.sourceforge.net/" rel="nofollow">Labview toolkit</a> here but it no longer works.

Use a socket server and socket client to talk between Labview and python. (Most cross-platform solution, and now you don't have to have your python and labview running on the same PC, or in the same process).

Unfortunately a sample is beyond me at the moment as I don't have labview installed, but I have done ole automation based integrations from LabView to dozens of apps in two or three languages, but that was many years ago. These days I would use the network socket technique.

I was using stdio communication with a Python process for a while and recently noticed Python for .Net ( <a href="http://pythonnet.github.io/" rel="nofollow">http://pythonnet.github.io/</a> ) which works for me.

Just copy the .dll in your LabVIEW project, create .Net constructors, and using the LabVIEW .Net you can quickly figure out how to use this library, which basically provides you with the unmanaged Python shared library, wrapped with .Net goodness.

blocks|key|630508|text|这是一个很好的快速解决方案，但有点不优雅。只需使用labview和python都可以读/写的文本文件。Labview将命令写入文本文件，python等待，直到读取命令，反之亦然。您可以同时拥有一个读取文本文件和一个写入文本文件。然而，这是一个较慢的解决方案，因为它需要时间来读取和写入。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|630509|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Here is a good quick solution but kind of unelegant. Just use a text file that both labview and python can read/write from. Labview writes commands to text file and python waits until a command is read or vice versa. you can have a read text file and a write text file at the same time. However this is a slower solution as it takes time to read and write.

There is a new Python/LabVIEW connector out, built mostly by yours truly, called <a href="https://www.winemantech.com/products/testscript-python-labview-connector" rel="nofollow noreferrer">TestScript</a>. It's a free, source-released Python/LabVIEW connector that is fully bidirectional. You can control LabVIEW from within a Python script, and you can call Python scripts from LabVIEW. It ships with several examples illustrating how you can send data from LabVIEW to Python and get a result back. In particular, the Simple Scripting Example - Add on Python Side.vi shows how TestScript accomplishes what you need.

Enjoy!
