# Concatenation of nested tuples

Given two variables

```
A = (2, 3)
B = (1, 4), (5, 8)
```

What is the simplest way to combine these two into a result variable `C`

so that:

```
C = ((2, 3), (1, 4), (5, 8))
```

Note that just calling:

```
C = A + B
```

leads to:

```
C = (2, 3, (1, 4), (5, 8))
```

which is **not the** desired result.

Also, note that tuples are preferred over lists, so `A`

, `B`

and `C`

can be used elsewhere as dictionary keys.
