I met this problem after changing main IDE from PyCharm to VSCode.
On example, to see what's wrong here, i have to hover on underlined "def": https://i.sstatic.net/no6eP.png
When i do this, i see this: https://i.sstatic.net/gRve5.png
..and i must scroll down a huge amount of text to see, what pycodestyle are telling (expected 2 blank lines): https://i.sstatic.net/7EJVm.png
(if i disable this https://i.sstatic.net/XpOjl.png, i would not see tooltips on hover at all: https://i.sstatic.net/NGpBS.png)
How can i see only pycodestyle tooltips, without this useless tons of default text? Or maybe i should use another linter?
somewhy, after disabling and enabling Python extension, linting in it and selecting pycodestyle as linter again, problem solved
