<p>Hey Stephen,</p>
<p>it's not a dumb question at all! The QGIS Python console+editor's
autocompletion is pretty misleading as it will suggest pretty much
anything it can find anywhere in the code base, with no regards if
the object or class you are currently working with actually has
that "thing". At least that how it seems to me. :}<br>
</p>
<p>In my experience it's best to ignore it for programming purposes
and only treat it as way to save typing some characters.</p>
<p><br>
</p>
<p>As for your errors, "xxx is not an attribute of yyy" means that
there is no yyy.xxx. This is not something you can import. yyy is
an object and will be checked live at runtime when Python tries to
access its xxx attribute (yyy.xxx). If .xxx does not exist for
yyy, then that's the way it is, you are on the wrong path :)</p>
<p>You can find out which attributes and methods your objects have
by using dir(yyy) or via the API documentation via help(yyy) or
online at <a class="moz-txt-link-freetext" href="https://qgis.org/pyqgis/master/index.html">https://qgis.org/pyqgis/master/index.html</a> (make sure to
choose the correct version corresponsing to your QGIS).<br>
</p>
<p>Cheers, Hannes<br>

<font size="4">Please pardon what may be a dumb question from a
self- (half-) taught student of Python. I often steal fragments
of code from the internet (especially including this forum) and
sometimes get an error message like "xxx is not an attribute of
yyy" . My problem, I think, is a missing " from xyz import
abc". My question to you now is whether there is some way to
know what to import, and from which module, for any particular
Python statement. More specifically, I get this error message:<br>
<br>
AttributeError: 'QgsEditFormConfig' object has no attribute
'setHidden'<br>
<br>
when I run the following code:<br>
<br>
from qgis.core import QgsProject<br>
from qgis.core import *<br>
from qgis.utils import iface<br>
from qgis.core import * <br>
from PyQt5.QtWidgets import QInputDialog<br>
from PyQt5.QtWidgets import *<br>
from qgis.PyQt.QtCore import * <br>
from qgis.gui import * <br>
<br>
def oneA( lyr, columnName, option ): <br>
flds= lyr.fields()<br>
indx = flds.indexOf(columnName)<br>
config = lyr.editFormConfig()<br>
config.setHidden(indx, option)<br>
lyr.setEditFormConfig(config)<br>
<br>
lyr = iface.activeLayer()<br>
aField = 'NAME' <br>
oneA (lyr, aField, True)<br>
<br>
When I type this code in the QGIS environment, autocompletion
leads me to believe that "setHidden" is allowed after "config."
but I must admit I don't understand the meaning of the several
choices specified in the parentheses. I'd be grateful if
someone would explain that to me. Also, am I correct in
thinking that an asterisk following "import" means "everything
in this module"?<br>
I'm running QGIS 3.16.3 under Windows 10.<br>
Thanks in advance for any help.</font></blockquote>
