Hello,
I have a python class that contains a dictionary.
I would like to use python properties to access the elements of the
dictionary.
This could be achieved as follows:
class MyClass(object):
def __init__(self):
self.d = {}
d['field1'] = 1.0
d['field2'] = 'A'
d['field3'] = [10.0,20.0,30.0]
@property
def field1(self):
return self.d['field1']
@field1.setter
def field1(self, value):
self.d['field1'] = value
@field1.deleter
def field1(self):
del self.d['field1']
@property
def field2(self):
return self.d['field2']
@field1.setter
def field2(self, value):
self.d['field2'] = value
@field1.deleter
def field2(self):
del self.d['field2']
@property
def field3(self):
return self.d['field3']
@field3.setter
def field3(self, value):
self.d['field3'] = value
@field3.deleter
def field3(self):
del self.d['field3']
However, I am effectively writing the same properties code three
times.
I would prefer to generate the properties code dynamically from the
keys of the dictionaries.
What I am looking for is something like:
class MyClass(object):
def __init__(self):
self.d = {}
d['field1'] = 1.0
d['field2'] = 'A'
d['field3'] = [10.0,20.0,30.0]
for f in d:
create_property(f)
where create_property(f) dynamically creates the property code for
field f in MyClass.
Is this possible?
If so, how could I do it?
Thanks,
James
