Creating a function that can convert a list into a dictionary in python

Creating a function that can convert a list into a dictionary in python

Pass

enumerated

list to

dict

constructor

>>> items = ['a','b','c']>>> dict(enumerate(items, 1))>>> {1: 'a', 2: 'b', 3: 'c'}

Here

enumerate(items, 1)

will yield

tuple

s of element and its index.
Indices will start from

1

( note the second argument of

enumerate

).
Using this expression you can define a function inline like:

>>> func = lambda x: dict(enumerate(x, 1))

Invoke it like:

>>> func(items)>>> {1: 'a', 2: 'b', 3: 'c'}

Or a regular function

>>> def create_dict(items):        return dict(enumerate(items, 1))
