Disable all Pylint warnings for a file
From the Pylint FAQ: With Pylint < 0.25, add # pylint: disable-all at the beginning of the module.

Disable auto wrap long line in Visual Studio Code
Check your Python formatting provider. “python.formatting.provider”: “autopep8” I guess in your case it is not Pylint which keeps wrapping the long lines, but autopep8. Try setting –max-line-length for autopep8 instead. “python.formatting.autopep8Args”: [ “–max-line-length=200” ]

What does Pylint’s “Too few public methods” message mean?

How do I disable “missing docstring” warnings at a file-level in Pylint?
It is nice for a Python module to have a docstring, explaining what the module does, what it provides, examples of how to use the classes.

Why is the empty dictionary a dangerous default value in Python? [duplicate]
Let’s look at an example: def f(value, key, hash={}): hash[value] = key return hash print(f(‘a’, 1)) print(f(‘b’, 2)) Which you probably expect to output: {‘a’: 1} {‘b’: 2} But actually outputs: {‘a’: 1} {‘a’: 1, ‘b’: 2}
