serious n00b.. NLTK in python 2.7 and 3.5 - pythlang - Oct-19-2016

Hey guys, I just joined this site and really hoping someone can at least guide me in the direction I'm supposed to be going after literally spending over 10 hours trying just to figure out how to use Python. I have lots of questions and I've been watching YouTube videos, tutorials, reading, etc just to get a basic understanding of Python in general.

Here is my question:

I've been trying to import NLTK but I am unable to do so and unsure of how to do so.

How do I use NLTK on Python 3.5? I've tried installing on 2.7 and I get permission errors.

Can I use Visual Studio Code to start programming?

What the heck do I do to get started?

Did my ineptitude in creating a virtualenv somehow fail and did I screw up bad?

I'm using a Mac with OS X Sierra and have successfully, as far as I know, downloaded and installed v3.5.

I can post messages, screenshots, whatever you guys need just to get pushed into the right direction.

Thanks so much for your patience in advance.

This seems like more than just "having trouble importing this 3rd party library". Please read through this.

What error permissions are you getting? What are you inputting to get that error? Get started with what? Python in general or using/installing this library?

You can use any IDE you want. You can use a text editor to write code, and execute it via command line/terminal.

RE: serious n00b.. NLTK in python 2.7 and 3.5 - pythlang - Oct-19-2016

Thanks for the reply. I was launching python before installing through pip.

My question remains:

How do I use Python 3.5 with NLTK and Visual Studio Code?

Below are my commands and errors with a then-successful attempt:

Thanks for this. I figured but wanted to double check.

if your using debian based you can get these from the repos

metulburr@ubuntu:~$ sudo apt-cache search nltk
python-nltk - Python libraries for natural language processing
python3-nltk - Python3 libraries for natural language processing
metulburr@ubuntu:~$

EDIT:
Whoops... disregard that i just caught you said you were on a mac. Doh

RE: serious n00b.. NLTK in python 2.7 and 3.5 - pythlang - Oct-19-2016

Haha, no worries but I will admit I've tried the

$ sudo apt-get ....

command in desperation

pip is defaulted to python2.7 pip...you need to use python3.x pip
I am not sure how to do that on a mac though.

RE: serious n00b.. NLTK in python 2.7 and 3.5 - pythlang - Oct-19-2016

In order to get to python 3.x I just type

$ python3

So after much waiting and patience on your guys' part, I have been able to finally download NLTK.

The only problem is that when I use the shell in IDLE NLTK will not import but if I use Terminal, it will.
IDLE:

>>> import nltk
Traceback (most recent call last):
  File "<pyshell#71>", line 1, in <module>
    import nltk
ImportError: No module named 'nltk'
>>> import sys
>>> sys.path
['', '/Users/jordanXXX/Documents', '/Library/Frameworks/Python.framework/Versions/3.5/lib/python35.zip', '/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5', '/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/plat-darwin', '/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/lib-dynload', '/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages']

Terminal:

Jordans-MBP:~ jordan$ python3
Python 3.5.2 (v3.5.2:4def2a2901a5, Jun 26 2016, 10:47:25)

>>> import nltk
>>>

Any suggestions? Do I need to append the path for Python 3.5 to use NLTK?

RE: serious n00b.. NLTK in python 2.7 and 3.5 - Larz60+ - Oct-19-2016

I think you want to use pip3 as well

RE: serious n00b.. NLTK in python 2.7 and 3.5 - pythlang - Oct-20-2016

Terminal:

Jordans-MBP:~ jordan$ pip3 install -U nltk
Requirement already up-to-date: nltk in /Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/nltk-3.2.1-py3.5.egg
Jordans-MBP:~ jordan$

So, how would I be able to use NLTK in the shell command since

$ import nltk

does nothing in the shell command IDLE and only works in terminal?

does it even matter if I use the shell command IDLE if i'm using terminal?
