flake8 disable linter only for a block of code

Question

I have a file in python like:

def test_constructor_for_legacy_json():
    """Test if constructor works for a legacy JSON in an old database"""

    a = A(**{
        'field1': 'BIG TEXT WITH MORE THAN 500 CHARACTERS....(...)',
        'field2': 'BIG TEXT WITH MORE THAN 500 CHARACTERS....(...)',
        'field3': 'BIG TEXT WITH MORE THAN 500 CHARACTERS....(...)',
        # (...)
        'field1000': 'BIG TEXT WITH MORE THAN 500 CHARACTERS....(...)',
    })

    assert type(a) == A

When I run flake8 + hacking I receive an error because the lines are too big.

If I put this command at the beginning of the file # flake8: noqa all file will be ignored from linter. But I only want to exclude from linter the block where a is declared.

I want to lint the rest of the file, and I cannot put at the end of each fieldx an # noqa: E501.

Some one know how can I solve this? Thanks

There isn't a way in flake8 to ignore a block of code

Your options are:

1. ignore each line that produces an error by putting # noqa: E501 on it

2. ignore the entire file (but this turns off all other errors as well) with a # flake8: noqa on a line by itself

3. ignore E501 in the entire file by using per-file-ignores:

   [flake8]
   per-file-ignores =
        path/to/file.py: E501
   

generally I'd prefer the third one, maybe even sequestering your long-strings into their own file to be ignored
