[ROS Q&A] 147 - How to make a Python file executable?

One of the most frequent question that we get in our customer support channels is an error when trying to 'rosrun' a Python file. The package is there, the file is there, the command has been typed in correctly, but it doesn't want to run. Sounds familiar?

This is usually due to the file's permission, which had to be set to be executable. So in this video, we will see how to do this, as well as explore a bit more on this subject. Beginners of ROS and the Linux system should find this very useful.

How could i find the path to exe file of python ? Normally, it is /devel/lib/package/file, but is just exe file of cpp.

Go to the directory of the .py file and turn it into executable by using chmod +x filename.py
