Hello.
I thought I understand this, but apparently I don't :(. I'm missing
something very basic and fundamental here, so redirecting me to the
related documentation is welcomed as well as providing working code :).
Trivial example which works as expected:
>>> x = {'a':123, 'b': 456}
>>> y = x
>>> x['a']=890
>>> y
{'a': 890, 'b': 456}
Now, let's try something more sophisticated (it's not real world example,
I've made up the problem which I think illustrates my issue). Let's say
I've got such a structure:
results = [ {'a': 12, 'b': 30 },
{'a': 13, 'b': 40 } ]
I'd like to have each row and column in separate object of self-made
classes.:
class mycolumn():
def __init__(self, resultset, row, col):
self.value = resultset[row][col]
def __str__(self):
return 'Column value: %s' % self.value
class myrow():
def __init__(self):
self.container = {}
def __str__ (self):
return self.container
results = [
{'a': 12, 'b' :30 },
{'a': 13, 'b' :40 }
]
mystruct = []
for row in results:
mystruct.append ( myrow() )
for col in row:
mystruct [len(mystruct)-1].container[col] = \
mycolumn(results, results.index(row), col)
print mystruct[0].container['b'] # 12
results[0]['b'] = 50 #
print mystruct[0].container['b'] # also 12 :/
In other words, I'd like to "map" the results to myrow and mycolumn
objects, and have these new objects' values changed when I change "results".
I hope I explained it well enough :). Thank you for your time.
