Python beginners tried it in 3 days from OS installation to running Twitter API

This is the article on the 18th day of dots girls Advent Calendar 2015.

Nice to meet you, this is 373_mina_mi. Qiita's first post suddenly got quite nervous on the Advent calendar. But write something to rllllho! !! I was told, so I will do my best to write it. ~~ It's too sloppy, but it's all because of Mr. rllllho who introduced me! ~~

About this article

• What should I do, I have no material to write in Advent Calender!
• I've started using Python recently, so it's time to try something!
• I've always wanted to try it, and I wonder if I can do something with the Twitter API.

With that said, it's a great article for anyone who earnestly raises the points that were caught when Python de amateurs created the development environment and moved the sample code in 3 days (actual work time 10h). I hope the person who gets caught with the same error will be saved ...

Execution environment

• Host OS: Windows 8.1 (64bit)
• VirtualBox 5.0.10
• OS: Ubuntu 14.04 LTS Japanese Remix
• Python 2.7.9

Basically Information gathering from Twitter with Python (Environment construction) Gathering information from Twitter with Python (Twitter API) I referred to the page of. Perhaps you can usually do it quickly with just that reference page ...

The procedure that finally worked

The error location and error details are difficult to see, so I summarized them later.

Build Python 2.7.9 from source code

Does OpenSSL not work with Python 2.7.6 when an error occurs? I found a typical sentence, so I put it back in. I tried it later and it worked on 2.7.6, so I don't think it's necessary here.

Beforehand

#Install OpenSSL
$sudo apt-get install libssl-dev

#install zlib
$ sudo apt-get install zlib1g-dev

Build from the source file with the necessary items in

$sudo wget https://www.python.org/ftp/python/2.7.9/Python-2.7.9.tgz
$tar xvzf Python-2.7.9.tgz
$cd Python-2.7.9
$./configure --prefix=/opt/python2.7.9 --enable-unicode=ucs4 --with-zlib --with-ensurepip=install
$make 
$sudo make install

This completes the installation.

$ /opt/python2.7.9/bin/python -V
Python 2.7.9

Also, I confirmed that Python 2.7.9 was installed properly!

Create an environment by using different Python versions with virtualenv

Install virtualenv

sudo apt-get install python-dev python-virtualenv

This time, I created a twi-py directory directly under my home directory and built a Python 2.7.9 environment. If you execute it obediently as it is, an error will occur.

$sudo easy_install virtualenv==1.10.1

After running

$virtualenv --python=/opt/python2.7.9/bin/python twi-py

To switch the Python environment, move to the created twi-py and then

$ source bin/activate

Now if the prompt says (twi-py), it's OK. If you check the Python version in this state, it should be 2.7.9!

Put Python library for OAuth authentication with pip install

With the above module installed Gathering information from Twitter with Python (Twitter API) I will omit it because it goes quickly on the street. If you don't enter, the error festival will be at the bottom ...

Executing sample code

Gathering information from Twitter with Python (Twitter API) Because it goes quickly on the street, ry I searched for `` dots. Women's Club''

For the time being, dots. Seems to have been caught. I'd like to understand the parameters properly and try various things again, but this time I'm here for the time being! This was the limit to make it in time for the Advent Calender _ (: 3 ”∠) _

Where and the cause of the error

so. It took three days to expose the cause that finally moved the sample. I can't deny anyone's advantage, but I'm sure there are people in the world who will encounter the same error ...! !!

Until ubuntu14.04 installation

"Just install VirtualBox and put Ubuntu on it" When I thought about it, the first thing that caught me was the screen resolution.

For some reason, the screen size cannot be changed from 640 x 480. The result How to change the screen size (resolution) of Ubuntu installed in VirtualBox to something other than 640x480 I found it and solved it safely by doing this street.

I can't create an environment with virtualenv

virtualenv --python=/opt/python2.7.9/bin/python twi-py When I try, I get an error.

$sudo easy_install virtualenv==1.10.1

After executing virtuslenv, it was built.

I feel like I was angry that I didn't have zlib in the first place, but I forgot the details because I failed to get the log ...

I can't pip install

It seems that pip is originally included in Python 2.7.9, but When I try to pip install according to the article I referred to

(twi-py)***@***VirtualBox:~/twi-py$ pip install requests requests_oauthlib
Traceback (most recent call last):

ImportError: cannot import name HTTPSHandler

It seems that pip is not included by default, so I checked Install Python 2.7.9 and Python 3.4.x with pip. Install pip referring to. If you try, this time I was angry without open ssl. Also, when I tried to create an environment with virtualenv, I felt angry that there was no zlib. So, in conclusion Beforehand

#Install OpenSSL
$sudo apt-get install libssl-dev

#install zlib
$ sudo apt-get install zlib1g-dev

Then re-install Python from configure! So, I arrived at the success example I wrote above.

Error when trying to run sample file

Finally, you can go through pip-install and run the sample! !! The error I encountered when I thought.

(twi-py)***@***VirtualBox:~/twi-py$ python twi-sample1.py
Error code: 401
Traceback (most recent call last):
  File "twi-sample1.py", line 63, in <module>
    main()
  File "twi-sample1.py", line 19, in main
    for tweet in tweets["statuses"]:
TypeError: 'NoneType' object has no attribute '__getitem__'

TypeError: 'NoneType' object has no attribute '__getitem__'? Is the object type different? But this doesn't seem to be a module error? ~~ * I'm a Python beginner who gets angry at the end of every sentence;

So, the conclusion. It was a copy of the API Key ...

And after this was discovered and the sample was successfully executed in Python 2.7.9, Maybe ... I thought I would make a virtualenv with Python 2.7.6 in the same way ... It worked as expected. I'm scared of copypemis! !! !! However, I got an error due to SSL or something, so I think it was because I didn't put that area properly with apt-get.

However, it took me more than two days to get Python 2.7.9 into pip, so if I could copy it properly, I felt like I could do something like that in three days, so I'll do my best. I'm depressed. But is it a hobby ...
