A silly example of a python decorator
A silly example of a python decorator.
Simply calls the decorated function twice.
Double down has been published to python package index and is available via pip:
pip install double_down
Otherwise, if you want to install it manually:
git clone firstname.lastname@example.org:smelnicki/double_down.git sudo python setup.py install
This is about as simple as it gets when it comes to decorators. It literally makes your function code execute twice.
For example, see below:
# example.py from double_down import double_down @double_down def hello(): print "Hello, Python" if __name__ == "__main__": hello()
Then in your terminal:
> python example.py Hello, Python Hello, Python
This project was just a fun little foray into learning how decorators work. In all honesty, it’d be a big stretch of the imagination to justify its use in some real life application.
If you’re curious how decorators work or want to get some hands on experience, I’d strongly encourage making one of your own. There’s plenty of documentation out there to use.
Download the file for your platform. If you're not sure which to choose, learn more about installing packages.
