NLTK Download Attribute error

[laila1a]

Hello all, I'm having a problem downloading NLTK. This is my first time downloading a module and I keep getting an error. I have been following https://www.youtube.com/watch?v=FLZvOKSCkxY to download NLTK on my MacBook Air. I successfully installed NLTK and I know that because when I type pip install nltk, this is the output:

Lailas-Air:~ laila$ pip install nltk
Requirement already satisfied: nltk in /Library/Python/2.7/site-packages (3.4)

Requirement already satisfied: singledispatch in /Library/Python/2.7/site-packages (from nltk) (3.4.0.3)

The next step in the video was to install nltk using a file I created under idle. I created the new file and typed import nltk, but I received the following output when I ran it(this showed up in idle, not the file):

Python 3.7.0 (v3.7.0:1bf9cc5093, Jun 26 2018, 23:26:24)

I was supposed to receive the same output the guy in the video did at 7:03.

go to the NLTK install page and follow instructions there: https://www.nltk.org/install.html
It's simple, then load corpora:

1. open python interpreter from command line
   
2. >>> import nltk
   
3. >>> nltk.download()
   

choose and install all or some corpora
