It looks like what you would get in Python 2.
If you're using Python 2, use 'raw_input' instead of 'input'.

problems with Methods in Python 3.4.2
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 "", line 1, in
dir(_builtins_)
NameError: name '_builtins_' is not defined
2)I am trying to do this:
>>> 'TTA',_add_('GGA')
Iam getting this :
Traceback (most recent call last):
File "", line 1, in
'TTA',_add_('GGA')
NameError: name '_add_' is not defined
3)I am trying to do this:
>>> -3 .abs()
Iam getting this
Traceback (most recent call last):
File "", line 1, in
-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 "", line 1, in
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,

You did not use the interactive help already available. help()
is also very useful.

These errors are due to using single underscores instead of double
underscores. I.e. use __builtins__ instead of _builtins_.

Integer objects don't have a built-in function named abs(). If you
want the absolute value of an integer, call abs directly, like so:
abs(-3)

Hello Dears,

It's __builtins__ not _builtins_ (double underscores at each end not
single underscores)
I am getting this:
Traceback (most recent call last):
File "", line 1, in
dir(_builtins_)
NameError: name '_builtins_' is not defined
2)I am trying to do this:

To call a method use "." not ",". And the method you are trying to
call is __add__ not _add_. But why... just do "TTA"+"GGA"
I’am getting this :
Traceback (most recent call last):
File "", line 1, in
'TTA',_add_('GGA')
NameError: name '_add_' is not defined
3)I am trying to do this:
>>> -3 .abs()
abs is a function not a method. do: abs(-3)
I’am getting this
Traceback (most recent call last):
File "", line 1, in
-3 .abs()
AttributeError: 'int' object has no attribute 'abs'
4) finally, after printing
>>>abs._doc_()
Again, use double underscores abs.__doc__()
I am getting this (and so on) :
Traceback (most recent call last):
File "", line 1, in
abs._doc_()
AttributeError: 'builtin_function_or_method' object has no attribute
'_doc_'

You need two underscore characters on each sides:
dir(__builtins__)

Same; magic methods have two underscore characters on each side.

abs(-3) abs is a function in Python.
See http://lucumr.pocoo.org/2011/7/9/python-and-pola/ for a good explanation...
