The del statement has no effect

From the Brython console:

Brython 3.7.0 on Netscape 5.0 (Windows)
>>> v

NameError: name 'v' is not defined
Traceback (most recent call last):
  module __main__ line 129, in myKeyPress
    _ = editor_ns['_'] = eval(currentLine, editor_ns)
  module <module> line 1
    v
>>> v = 1
>>> v
1
>>> del v
>>> v
1

But after del v accessing v should raise a NameError again.

My mistake, sorry : when I tested your example I removed the parenthesis:

del hello["a"]

instead of

del(hello["a"])

and the bug happened with the parenthesis.

Thanks for the report !

To be fair, before suspecting Chromium, I’ll try the javascript equivalent of Python’s del(). What javascript equivalent does Brython use for del()?
