Single-element tuples are printed incorrectly

[taion]

In:

a = 1,

Out:

a = 1

The trailing comma is necessary for single-element tuples in Python, with out without the parens (i.e. (1,), not (1)).

Tuple printing is somewhat questionable in general.

In:

a = (
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
)

Out:

a = "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf"

Lists too, actually:

# In:
a = [
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
    "asdfasdfasdfasdfasdfasdf",
]

# Out:
a = ["asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf", "asdfasdfasdfasdfasdfasdf"]

These are all with defaults, i.e. max width of 80 (other than enabling the Python plugin).

Might be missing a group()?

[taion]

For the wrapping things, yeah.

The single-element tuple thing in the OP is actually a syntax issue, though. The printed code is not equivalent to the input code.

[taion]

Empty tuples are broken as well:

# In:
a = ()

# Out:
a =

[taion]

This isn't fully resolved. Empty tuples I believe now will get printed like a = ,, which is still invalid syntax.
