Question

How can I do the following in a more concise, “pythonic” way:

for element in some_list:
        if some_condition:
                element.some_attr = some_value

Answer 1

The only thing that’s not pythonic in your code is that you’re not using 4 spaces for indentation.

“Pythonic” doesn’t always mean “concise”; for example the following is shorter, but less readable than your loop:

[setattr(e, 'some_attr', some_value) for e in some_list if some_condition]

So, stick to the code you have.
