This aspect does not have any sub aspects.
def func(a, b, c, d, e, f, g, h, i, j, k): pass
Methods that take too many parameters are difficult to read, maintain and work with, and callers of those method often have an awkward time assembling all of the data and the resulting code is usually not pretty.
How to fix this
This can be fixed by:
Instead of passing a group of data received from an object as parameters, pass the object itself to the method. Sometimes you can merge several parameters into a single object etc.
