E127 continuation line over indented for visual indent как исправить

For lines that are too long (e.g. > 79 characters), you can use parentheses to group your conditions:

if (first_index < 0 
        or second_index > self._number_of_plates - 1
        or condition2
        and candition3):
    raise ValueError

Note that any boolean conditions (or, and) should go at the start of the line before the condition.

In your case, there is a special rule because of the if (...) construct:

When the conditional part of an if-statement is long enough to require
that it be written across multiple lines, it’s worth noting that the
combination of a two character keyword (i.e. if), plus a single space,
plus an opening parenthesis creates a natural 4-space indent for the
subsequent lines of the multiline conditional. This can produce a
visual conflict with the indented suite of code nested inside the
if-statement, which would also naturally be indented to 4 spaces. This
PEP takes no explicit position on how (or whether) to further visually
distinguish such conditional lines from the nested suite inside the
if-statement. Acceptable options in this situation include, but are
not limited to:

# No extra indentation.
if (this_is_one_thing and
    that_is_another_thing):
    do_something()

# Add a comment, which will provide some distinction in editors
# supporting syntax highlighting.
if (this_is_one_thing and
    that_is_another_thing):
    # Since both conditions are true, we can frobnicate.
    do_something()

# Add some extra indentation on the conditional continuation line.
if (this_is_one_thing
        and that_is_another_thing):
    do_something()

(Also see the discussion of whether to break before or after binary
operators below.)
