Iterate over a dictionary in Python
This question already has an answer here:
You iterate through a dictionary just like an array, but instead of giving you the values in the dictionary it gives you the keys.
> my_dict = {"a" : 4, "b" : 7, "c" : 8}
> for i in my_dict:
... print i
a
b
c
You can then access the data in the dictionary like you normally would. (This is achieved with square brackets, so my_dict["a"] would give 4.)
Dictionary has the ability to iterate over itself to print each item. To simply print the details of each item as you have asked, simply use the print command:
>>> ourNewDict = {'name': 'Kyle', 'rank': 'n00b', 'hobby': 'computing'}
>>> print ourNewDict
Output: {'hobby': 'computing', 'name': 'Kyle', 'rank': 'n00b'}
Or, to print keys and values independently:
>>> print ourNewDict.keys()
Output: ['hobby', 'name', 'rank']
>>> print ourNewDict.values()
Output: ['computing', 'Kyle', 'n00b']
If I read into your question more, and guess that you'd like to iterate through each object to do more than simply print, then the items() command is what you need.
>>> for key, value in ourNewDict.items():
... print key
...
hobby
name
rank
>>> for key, value in ourNewDict.items():
... print value
...
computing
Kyle
n00b
>>>
And to be very generic:
>>>for someVariableNameHere in someDictionaryNameHere.items():
... doStuff
