# Python | Flatten Tuples List to String

• Last Updated : 11 Nov, 2019

Sometimes, while working with data, we can have a problem in which we need to perform interconversion of data. In this, we can have a problem of converting tuples list to a single String. Let’s discuss certain ways in which this task can be performed.

Method #1 : Using list comprehension + `join()`
The combination of above functionalities can be used to perform this task. In this, we join all the individual string elements using `join()` and extraction of each element is done using list comprehension.

Output :

```The original list : [('1', '4', '6'), ('5', '8'), ('2', '9'), ('1', '10')]
Tuple list converted to String is : 1 4 6 5 8 2 9 1 10
```

Method #2 : Using `chain() + join()`
This is yet another method to perform this particular task. In this, we perform the task of extracting each of element of tuple list using `chain()` rather than list comprehension.

Output :
```The original list : [('1', '4', '6'), ('5', '8'), ('2', '9'), ('1', '10')]
Tuple list converted to String is : 1 4 6 5 8 2 9 1 10
```
