Attrs library for Python
A quick advertisement.
I love Hynek Schlawack's attrs library. It's had a subtle but greatly clarifying influence on my code since I discovered it.
If you're not familiar with that library then I highly recommend reading about it.
It means you can write simple objects like
@attr.s
class Thing(object):
value = attr.ib()
Which are equivalent to
class Thing(object):
def __init__(self, value):
self.value = value
def __str__(self):
# ... The usual thing
def __eq__(self):
# ... The usual thing
# ... All the other dunder methods
The docs have much better examples than I could repeat here. You should check it out.
