# Python | Convert list to indexed tuple list

• Last Updated : 02 Oct, 2019

Sometimes, while working with Python lists, we can have a problem in which we need to convert a list to tuple. This kind of problem have been dealt with before. But sometimes, we have it’s variation in which we need to assign the index of element along with element as a tuple. Let’s discuss certain ways in which this task can be performed.

Method #1 : Using `list() + enumerate()`
Combination of above functions can be used to perform this particular task. In this, we just pass the enumerated list to list(), which returns the tuple with first element as index and second as list element at that index.

Output :

```
The original list : [4, 5, 8, 9, 10]
List after conversion to tuple list : [(0, 4), (1, 5), (2, 8), (3, 9), (4, 10)]
```

Method #2 : Using `zip() + range()`
The combination of above functions can also be used to perform this particular task. In this, we just use the ability of `zip()` to convert to tuple and `range()` to get element index till length. This pairs index to value in form of tuple list.

Output :
```

List after conversion to tuple list : [(0, 4), (1, 5), (2, 8), (3, 9), (4, 10)]
```
