Combining two dictionaries

[psbasha]

HI,

I have two or more dictionaries.I have to combine the ldictionaries and make one list.I am trying to do the following and I am getting the following error.How to fix this bug?

dict1 = {100:[1,2],200:[2,3]}
dict2 = {300:[1,2],400:[2,3]}
dict3 = dict1 + dict2

Traceback (most recent call last):
File "<pyshell#6 >", line 1, in -toplevel-
dict3 = dict1 + dict2
TypeError: unsupported operand type(s) for +: 'dict' and 'dict'

Thanks
PSB

hello, you should read the reference library here on dict, or use help(dict) before asking here. the update() method is what you need.

>>> a = {'1':'one'}
>>> b = {'2':'two'}
>>> a.update(b)
>>> a
{'1': 'one', '2': 'two'}
