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')
Iam 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()
Iam 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,
