How to access self.key

Postby micksulley » Wed Apr 24, 2013 11:45 pm

I have a class and then a dictionary of instances of the class. Within a method in the class I would like to check the key of the current object, something like

Code: Select all
class xyz:
def methd(self):
  if self.key = 'ABC':
    print('This is ABC')

d = {}

d['ABC'] = xyz()

but self.key does not work. How do I do it?

Class names should be CamelCase.
Your indentations is wrong def is at the same level as class.
Indents should be 4 spaces.
You have not initialized self.key with a value.
A single '=' is for assigning a value to check for a value use double '=='.
The dictionary key 'ABC' is just the key that the instance of class Xyz is stored against in d, the instance of Xyz knows nothing about dictionary d.

her is a raw example, and when i saw raw i mean raw. I am not sure exactly what you are doing, but here is something like what i think you are doing, not sure though.

Code: Select all
class Employee:
   def __init__(self, name): = name

names = ['john', 'jacob', 'jingleheimer', 'schmidt']
instances = {}

for name in names:
   instances.update( {name:Employee(name)} )
print('instances are: {}'.format(instances))
print('instances[\'john\'] is: {}'.format(instances['john']))

where instances['john'] is the dictionary key to the value, being the instance object, which currently only contains the same name as the key anyways.
