No global found (e.g., using a module without importing it)
P**ing the wrong number of parameters to functions/methods/constructors
P**ing the wrong number of parameters to builtin functions & methods
Using format strings that don't match arguments
Using cl** methods and attributes that don't exist
Changing signature when overriding a method
Redefining a function/cl**/method in the same scope
Using a variable before setting it
self is not the first parameter defined for a method
Unused globals and locals (module or variable)
Unused function/method arguments (can ignore self)
No doc strings in modules, cl**es, functions, and methods
