I want to swap every two characters in a string and store the output in a list (to check every string later wether it exists in the dictionary)

I have seen some codes that swap the characters all at once, but that is not what I'am looking for.

For example:

```
var = 'abcde'

```

Expected output:

```
['bacde','acbde','abdce','abced']

```

How can I do this in Python?
