Delete everything between two brackets in Vim, including newlines

Question

Say I have the following python array literal:

def f():
    arr = [
        1,          
        2,
        3   
    ]  

I want to delete everything in the brackets so that it becomes this:

def f():
    arr = [] 

How can I do that with minimal commands in vim?

---

These are some of my attempts:

• Using di] will delete the text, but not the empty newlines, leaving a lot of whitespace I'd have to delete:

  def f():
      arr = [         
      ]
  

• Using da] will delete the newlines, but also the brackets:

  def f():
      arr =
  

Answer 1

You can simply do:

ca[[]<Esc>

or:

ca][]<Esc>
