Tool to convert Python code to be PEP8 compliant

Question

I know there are tools which validate whether your Python code is compliant with PEP8, for example there is both an online service and a python module.

However, I c

@Andy Hayden gave good overview of autopep8. In addition to that there is one more package called pep8ify which also does the same thing.

However both packages can remove only lint errors but they cannot format code.

little = more[3:   5]

Above code remains same after pep8ifying also. But the code doesn't look good yet. You can use formatters like yapf, which will format the code even if the code is PEP8 compliant. Above code will be formatted to

little = more[3:5]

Some times this even destroys Your manual formatting. For example

BAZ = {
    [1, 2, 3, 4],
    [5, 6, 7, 8],
    [9, 10, 11, 12]
}

will be converted to

BAZ = {[1, 2, 3, 4], [5, 6, 7, 8], [9, 10, 11, 12]}

But You can tell it to ignore some parts.

BAZ = {
   [1, 2, 3, 4],
   [5, 6, 7, 8],
   [9, 10, 11, 12]
}  # yapf: disable
