How To Solve Python Error: AttributeError: enter Error ?

  1. How To Solve Python Error: AttributeError: enter Error ?

    To Solve Python Error: AttributeError: enter Error More code would be appreciated (specifically the ParamExample implementation), but I'm assuming you're missing the __enter__ (and probably __exit__) method on that class.

Solution 1

More code would be appreciated (specifically the ParamExample implementation), but I’m assuming you’re missing the __enter__ (and probably __exit__) method on that class.

When you use a with block in python, the object in the with statement gets its __enter__ method called, the block inside the with runs, and then the __exit__ gets called (optionally with exception info if one was raised). Thus, if you don’t have an __enter__ defined on your class, you’ll see this error.

Side note: you need to either indent the second with block so it’s actually inside the first, OR replace these two lines with

with ParamExample(URI) as pe, MotionCommander(pe, default_height=0.3) as mc:

which is the same as nesting these two context managers (the name of the objects used by with blocks).
