Indentation Off with Multi-Line Strings

[bwendling]

When pylint calculates the correct indentation of a line following a multi-line string it uses the last non-space character in the multi-line string rather than basing it off of the code preceding the string. In the following example, I would expect the indentation of some and string to be four spaces, because that's the correct indentation based off of the _ = """Dear Guido, line. But pylint wants it to be four spaces beyond the start of Bill""", which makes the code less readable IMO.

Steps to reproduce

1. cat > /tmp/z.py
_ = """Dear Guido,

Python is pretty awesome, but there's something annoying with the linter.

                                 Sincerely,
                                 Bill""".format(
    some=variable_with_a_long_name,
    strings=another_variable_with_a_really_long_name)
2. pylint /tmp/z.py

Current behavior

Outputs the following message:

************* Module z
C:  7, 0: Wrong hanging indentation (add 33 spaces).
    some=variable_with_a_long_name,
    ^                                | (bad-continuation)
C:  8, 0: Wrong hanging indentation (add 33 spaces).
    strings=another_variable_with_a_really_long_name)
    ^                                | (bad-continuation)

Expected behavior

This should have been acceptable.

pylint --version output

Sounds like a good improvement, thanks.

bad-continuation has been removed in #3571, black or another formatter can help you with this better than Pylint
