Cognitive Complexity
Cognitive Complexity is a measure of how difficult a unit of code is to intuitively understand. Unlike Cyclomatic Complexity, which determines how difficult your code will be to test, Cognitive Complexity tells you how difficult your code will be to read and comprehend.
A method's cognitive complexity is based on a few simple rules:
- Code is not considered more complex when it uses shorthand that the language provides for collapsing multiple statements into one
- Code is considered more complex for each "break in the linear flow of the code"
- Code is considered more complex when "flow breaking structures are nested"

It's confusing to have a class member with the same name (case differences aside) as its enclosing class. This is particularly so when you consider the common practice of naming a class instance for the class itself.
Best practice dictates that any field or member with the same name as the enclosing class be renamed to be more descriptive of the particular aspect of the class it represents or holds.

class Foo: foo = '' def getFoo(self): ... foo = Foo() foo.getFoo() # what does this return?
Compliant Solution

A long parameter list can indicate that a new structure should be created to wrap the numerous parameters or that the function is doing too many things.
Noncompliant Code Example
With a maximum number of 4 parameters:
def do_something(param1, param2, param3, param4, param5): ...
Compliant Solution
def do_something(param1, param2, param3, param4): ...

Trailing whitespace is superfluous.
The warning returned varies on whether the line itself is blank,
for easier filtering for those who want to indent their blank lines.
