word_cloud
A little word cloud generator in Python. Read more about it on the blog post or the website. The code is Python 2, but Python 3 compatible.
Installation
Fast install:
pip install wordcloud
If you are using conda, it might be even easier to use anaconda cloud:
conda install -c https://conda.anaconda.org/amueller wordcloud
For a manual install get this package:
wget https://github.com/amueller/word_cloud/archive/master.zip
unzip master.zip
rm master.zip
cd word_cloud-master
Install the package:
python setup.py install
Note that if you are not on Ubuntu, you need to pass a font_path to the WordCloud object (docs) to point to
some existing font.
Examples

Command-line usage
The wordcloud_cli.py tool can be used to generate word clouds directly from the command-line:
$ wordcloud_cli.py --text mytext.txt --imagefile wordcloud.png
If you're dealing with PDF files, then pdftotext, included by default with many Linux distribution, comes in handy:
$ pdftotext mydocument.pdf - | wordcloud_cli.py --imagefile wordcloud.png
In the previous example, the - argument orders pdftotext to write the resulting text to stdout, which is then piped to the stdin of wordcloud_cli.py.
Use wordcloud_cli.py --help so see all available options.

Issues
Using Pillow instead of PIL might might get you the TypeError: 'int' object is not iterable problem also showcased on the blog.
Licensing
The wordcloud library is MIT licenced, but contains DroidSansMono.ttf, a true type font by Google, that is apache licensed.
The font is by no means integral, and any other font can be used by setting the font_path variable when creating a WordCloud object.
