attribute lookup str and objects like object.myvar

Question

I want to know how i can concat object fields with a variable, it's hard to explain to me, let me give an example

Example:

My object have:

myobject.name = 'Red'
myobject.lastname = 'Foo'

and I have a function like this:

my function
..........
some_dumb_field = name

print myobject.some_dumb_field

And this crashes!, how can i concat the str of the field like an object?

Answer 1

I'm guessing you are looking for getattr:

print getattr(myobject, some_dumb_field)

This will look up the attribute of myobject whose name is given by the string some_dumb_field.

For example,

getattr(myobject, 'name')

is equivalent to

myobject.name

(Warning: This could be called attribute lookup; you won't find it under the term "concat".)
