Python code refactoring question. Applying functions to multiple elements
I have code that looks something like this:
self.ui.foo.setEnabled(False)
self.ui.bar.setEnabled(False)
self.ui.item.setEnabled(False)
self.ui.item2.setEnabled(False)
self.ui.item3.setEnabled(False)
And I would like to turn it into something like this:
items = [foo,bar,item,item2,item3]
for elm in items:
self.ui.elm.setEnabled(False)
But obviously just having the variables in the list with out the 'self.ui' part is invalid, and I would rather not开发者_如何学C type out 'self.ui' for every element in the list, because that really isn't to much better. How could I rewrite my first code to make it something like what I'm talking about?
Grab the object to have the function called on it by its attribute name using the built-in getattr function:
items = ['foo', 'bar', 'item', 'item2', 'item3']
for elm in items:
getattr(self.ui, elm).setEnabled(False)
You could try something like:
items = [foo,bar,item,item2,item3]
ui = self.ui
for elm in items:
ui.elm.setEnabled(False)
