ipython tab completion of method parameters showing builtins

IPython tab completion for method parameters is showing more information than I'm expecting to see:

In [1]: from my_package import MyClass

In [2]: cf = MyClass(<TAB>
                       abs()                                 api_key=
                       all()                                 api_key_filename=
                       any()                                 ArithmeticError                       >
                       api_endpoint=                         ascii()
                       ...

This also happens on instance methods:

In [3]: cf.auth(<TAB>
                 abs()                                 ascii()
                       ...

Q) Should I be seeing builtin methods like abs() when I tab complete on my instance methods and constructors?.

My IPCompleter configuration looks like this:

In [4]: %config IPCompleter

Yes you should, because having function call in methods or constructor is perfectly valid. Actually you can write any expressions in any field when you call a callable.

MyProgressMeter(any(params))
range(abs(value_a - value_b))
obj.frobulate(len(set(items)))
print(len(my_list))

Are reasonable, so on MyProgressMeter(<tab>, obj.frobulate(<tab>, print(<tab> and range(<tab> you're shown everything that is in local/global namespace that make sense, as well as named parameters. Instance methods are no different of course.

Note: it is not well known but range is actually a constructor:

>>> type(range)
<class 'type'>
