I will put imports into my __init__ files, so that I can import things from the
module directly instead of having to import from a file in the module.
I almost never put code in the __init__'s, I have a couple of times put in
something that was designed to modify which routine was imported

Is it possible to override the assignment of built in types to the shorthand
representations? And if not, is it a reasonable thought to consider adding?
For example, right now, if I do:
test = "this is a string",
I get back str("this is a string"). What if I want to return this as

First of all, I suggest splitting this into a separate proposal (new thread)
that way you will avoid confusion for people who are still considering the
older proposal, and for the (probably many) people who have stopped reding the
old thread due to some of the more heated conversations in

I could easily see using all of the examples; I run into this pretty regularly.
What about something like the following (which, honestly is really a
combination of other examples).

I'm not 100% sure what you are trying to do.. so let me throw out a few things

If you are trying to run a bunch of similar tests on something, changing only
(or mostly) in the parameters passed, you can use self.subTest().
Like this:
Def test_this(self):
I have never used it personally. It always looked interesting, but I never ran
into a need to generate the source for it.

Take a look at the docs for
print() https://docs.python.org/3.5/library/functions.html#print
str() https://docs.python.org/3.5/library/stdtypes.html#str
repr() https://docs.python.org/3.5/library/functions.html#repr
When you do "print(object)", python will run everything through str() and

In addition to Peter's points,

and/or functions. That makes it easier to read and troubleshoot. (you can
always re-optimize It if needed.)
- Peter's point about making things into functions will also help
As with lots of things in python, there are lots of ways of approaching this,
here are some hints for you to think about (in no particular order):

- replace()
- string[:y]
- split()

I agree the error is not very clear, since the "=" was not passed, it seems
