# Python | Ways to join pair of elements in list

• Last Updated : 25 Jun, 2019

Given a list, the task is to join a pair of elements of the list. Given below are a few methods to solve the given task.

Method #1: Using `zip()` method

 `# Python code to demonstrate ``# how to join pair of elements of list`` ` `# Initialising list``ini_list ``=` `[``'a'``, ``'b'``, ``'c'``, ``'d'``, ``'e'``, ``'f'``]`` ` `# Printing initial list ``print` `(``"Initial list"``, ``str``(ini_list))`` ` `# Pairing the elements of lists``res ``=` `[i ``+` `j ``for` `i, j ``in` `zip``(ini_list[::``2``], ini_list[``1``::``2``])]`` ` `# Printing final result``print` `(``"Result"``, ``str``(res))`
Output:
```Initial list ['a', 'b', 'c', 'd', 'e', 'f']
Result ['ab', 'cd', 'ef']
```

Method #2: Using list comprehension and next and iters

 `# Python code to demonstrate ``# how to join pair of elements of list`` ` `# Initialising list``ini_list ``=` `iter``([``'a'``, ``'b'``, ``'c'``, ``'d'``, ``'e'``, ``'f'``])`` ` `# Pairing the elements of lists``res ``=` `[h ``+` `next``(ini_list, '') ``for` `h ``in` `ini_list]`` ` `# Printing final result``print` `(``"Result"``, ``str``(res))`
Output:

```Result ['ab', 'cd', 'ef']
```

Method #3: Using list comprehension

 `# Python code to demonstrate ``# how to join pair of elements of list`` ` `# Initialising list``ini_list ``=` `[``'a'``, ``'b'``, ``'c'``, ``'d'``, ``'e'``, ``'f'``]`` ` `# Printing initial lists``print` `(``"Initial list"``, ``str``(ini_list))`` ` `# Pairing the elements of lists``res ``=` `[ini_list[i] ``+` `ini_list[i ``+` `1``] ``       ``for` `i ``in` `range``(``0``, ``len``(ini_list), ``2``)]`` ` `# Printing final result``print` `(``"Result"``, ``str``(res))`
Output:
```Initial list ['a', 'b', 'c', 'd', 'e', 'f']
Result ['ab', 'cd', 'ef']
```
