problems with Methods in Python 3.4.2

[Marcus Lütolf]

Hello Dears,

I solved the problem: There are two underscore key strokes required.
Marcus.

Hello Dears,

1)I am trying to do this:



>>> dir(_builtins_)



I am getting this:

Traceback (most recent call last):

  File "<pyshell#0>", line 1, in <module>

    dir(_builtins_)

NameError: name '_builtins_' is not defined



2)I am trying to do this:



>>> 'TTA',_add_('GGA')



I’am getting this :

Traceback (most recent call last):

  File "<pyshell#0>", line 1, in <module>

    'TTA',_add_('GGA')

NameError: name '_add_' is not defined



3)I am trying to do this:



>>> -3  .abs()



I’am getting this

Traceback (most recent call last):

  File "<pyshell#1>", line 1, in <module>

    -3 .abs()

AttributeError: 'int' object has no attribute 'abs'



4) finally, after printing



>>>abs._doc_()



I am getting this (and so on) :

Traceback (most recent call last):

  File "<pyshell#2>", line 1, in <module>

    abs._doc_()

AttributeError: 'builtin_function_or_method' object has no attribute '_doc_'

What did I do wrong ? Thanks for help, Marcus Luetolf, M.D., 90 Bondastreet,
