If you work with javascript and python, you probably hate that the dicts in python are not accesible by dot-notation dict.prop, well you can fix that python bug easily by using the next class
class Bunch(dict):
"""Util class to have a hashable dictionary accesible by dot-notation."""
__getattr__ = dict.get
__setattr__ = dict.__setitem__
def __hash__(self):
return hash(tuple(sorted(self.items())))
You can use it like this
dic = {
'pepe': 1,
'foo': 'dsa',
'bar': 2.0,
}
obj = Bunch(dic)
print(obj.pepe)
>>> 1
or (the same)
obj = Bunch({
'pepe': 1,
'foo': 'dsa',
'bar': 2.0,
})
print(obj.pepe)
>>> 1
and by being hashable, you can even use it together with @lru_cache
from functools import lru_cache
@lru_cache()
def inc_pepe(dic):
print(dic.pepe)
return dic.pepe + 1
obj = Bunch({
'pepe': 1,
'foo': 'dsa',
'bar': 2.0,
})
print(inc_pepe(obj))
>>> 1
>>> 2
print(inc_pepe(obj))
>>> 2
