[Tutor] Help Command Question

[l***@gmail.com]

Hi Everyone,


I'm trying to print a command of list options by using the help command in the iPython interpreter. Read captured copy of the printout as follows:



'Python 2.7.10 |Anaconda 2.3.0 (64-bit)| (default, May 28 2015, 16:44:52) [MSC v.
1500 64 bit (AMD64)]
Type "copyright", "credits" or "license" for more information.

In [1]: help list
File "<ipython-input-1-823a3ff84bc4>", line 1
help list
^
SyntaxError: invalid syntax.'


Question: What is the correct help command?


Regards,

Hal

Try:

Snipped from my ipython session:

Good luck,

My fellow Pythonistas, ask not what our language can do for you, ask
