You could use enumerate starting at 1 and convert index as string, in a dictionary comprehension:

list1=["Indrajit","Mayur","Swapnali","Akankasha"]

dict1 = {str(k):v for k,v in enumerate(list1,1)}

print(dict1)

result:

{'1': 'Indrajit', '4': 'Akankasha', '2': 'Mayur', '3': 'Swapnali'}

Try this

List<string> list = new List<string>() { "Indrajit", "Mayur", "Swapnali", "Akankasha" };
            Dictionary<int, string> di = new Dictionary<int, string>();
            for (int i = 1; i <= list.Count; i++)
            {
                di.Add(i, list[i - 1]);
            }

Just use

dict1 = dict(enumerate(list1))

enumerate will return a generator that returns a tuple with index and list value, one at a time. By calling dict() you totally consume the generator, getting what you want.

You can use enumerate method to do this:

>>> dict(enumerate(list1,1))
{1: 'Indrajit', 2: 'Mayur', 3: 'Swapnali', 4: 'Akankasha'}

Also you can use list.index() method:

>>> list1=["Indrajit","Mayur","Swapnali","Akankasha"]
>>> print({list1.index(i)+1,i} for i in list1 )

>>> print({list1.index(i)+1:i for i in list1})
{1: 'Indrajit', 2: 'Mayur', 3: 'Swapnali', 4: 'Akankasha'}

But if there're duplicate items in your list, it maybe return unexpected result.
