Hello Dears,
1)I am trying to do this:
>>> dir(_builtins_)
It's __builtins__ not _builtins_ (double underscores at each end not
single underscores)
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')
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 "<pyshell#0>", line 1, in <module>
'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 "<pyshell#1>", line 1, in <module>
-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 "<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
