# Python – Adding Tuple to List and vice – versa

• Last Updated : 10 Jul, 2020

Sometimes, while working with Python containers, we can have a problem in which we need to perform addition of one container with another. This kind of problem can have occurrence in many data domains across Computer Science and Programming. Let’s discuss certain ways in which this task can be performed.

Method 1 : Using += operator [list + tuple]
This operator can be used to join a list with a tuple. Internally its working is similar to that of list.extend(), which can have any iterable as its argument, tuple in this case.

 `# Python3 code to demonstrate working of ``# Adding Tuple to List and vice - versa``# Using += operator (list + tuple)`` ` `# initializing list``test_list ``=` `[``5``, ``6``, ``7``]`` ` `# printing original list``print``(``"The original list is : "` `+` `str``(test_list))`` ` `# initializing tuple ``test_tup ``=` `(``9``, ``10``)`` ` `# Adding Tuple to List and vice - versa``# Using += operator (list + tuple)``test_list ``+``=` `test_tup`` ` `# printing result ``print``(``"The container after addition : "` `+` `str``(test_list)) `
Output :
```The original list is : [5, 6, 7]
The container after addition : [5, 6, 7, 9, 10]
```

Method #2 : Using `tuple()`, data type conversion [tuple + list]
The following techinque is used to add list to a tuple. The tuple has to converted to list and list has to be added, at last resultant is converted to tuple.

 `# Python3 code to demonstrate working of ``# Adding Tuple to List and vice - versa``# Using tuple(), data type conversion [tuple + list]`` ` `# initializing list``test_list ``=` `[``5``, ``6``, ``7``]`` ` `# printing original list``print``(``"The original list is : "` `+` `str``(test_list))`` ` `# initializing tuple ``test_tup ``=` `(``9``, ``10``)`` ` `# Adding Tuple to List and vice - versa``# Using tuple(), data type conversion [tuple + list]``res ``=` `tuple``(``list``(test_tup) ``+` `test_list)`` ` `# printing result ``print``(``"The container after addition : "` `+` `str``(res)) `
Output :
```The original list is : [5, 6, 7]
The container after addition : (9, 10, 5, 6, 7)
```
