Sometimes you want to reference your items in the list or other data structure for later use. It makes easier by providing an enumerate function in Python.Â
Let’s take a look at the parameter of enumerate.
enumerate(iterable, startIndex)
- Iterable: list or other iterable.
- StartIndex: It is the starting number. StartIndex is optional.
Let’s take a look at the code.
| name = [‘Alex’, ‘Bob’ ,’Celvin’, ‘Dexter’] e_name = enumerate(name) print(e_name) |
The enumerate function returns an enumerate object that we need to iterate to get the output values. Let us iterate through the list.
| name = [‘Alex’, ‘Bob’ ,’Celvin’, ‘Dexter’] e_name = enumerate(name) for i in e_name: print(i) |
Now let’s start counting from 5 now.
| name = [‘Alex’, ‘Bob’ ,’Celvin’, ‘Dexter’] e_name = enumerate(name,5) for i in e_name: print(i) |
The following is the output
Enumerating a Tuple
The enumerate on tuple works the same as on lists.
| name = (‘Alex’, ‘Bob’ ,’Celvin’, ‘Dexter’) e_name = enumerate(name) for i in e_name: print(i) |
Enumerating a String
Let’s take a look at the code to enumerate in python string.
| name = (‘Hello’) e_name = enumerate(name) for i in e_name: print(i) |
