python - Why can't I use ._doc_ attribute for built in functions?

Question

For example:

print(print._doc_)

this is the error I get:

PS D:GitHubMango> py temp.txt
Traceback (most recent call last):
  File "D:GitHubMangoemp.txt", line 1, in <module>
    print(print._doc_)
AttributeError: 'builtin_function_or_method' object has no attribute '_doc_'

Answer 1

You want __doc__ (two underscores on either side):

>>> print(print.__doc__)
print(value, ..., sep=' ', end='
', file=sys.stdout, flush=False)
