Python Iterate Dictionary by Index

Question

I want to iterate through a dictionary in python by index number.

Example :

 dict = {'apple':'red','mango':'green','orange':'orange'} 

I want to iterate through the dictionary from first to last, so that I can access the dictionary items by their indexes. For example, the 1st item will be apple, and the 2nd item will be mango and value will be green.

Something like this:

for i in range(0,len(dict)):     dict.i 

Answer 1

You can iterate over keys and get values by keys:

for key in dict.iterkeys():     print key, dict[key] 

You can iterate over keys and corresponding values:

for key, value in dict.iteritems():     print key, value 

You can use enumerate if you want indexes (remember that dictionaries don't have an order):

>>> for index, key in enumerate(dict): ...     print index, key ...  0 orange 1 mango 2 apple >>>  

Answer 2

There are some very good answers here. I'd like to add the following here as well:

some_dict = {     "foo": "bar",     "lorem": "ipsum" }  for index, (key, value) in enumerate(some_dict.items()):     print(index, key, value) 

results in

0 foo bar 1 lorem ipsum 

Appears to work with Python 2.7 and 3.5
