I am trying to use a triple-quoted strings in Python3(.7) to build some formated strings.

I have a list of inner strings, which all need to be tabbed in:

```
    This is some text
    across multiple
    lines.

```

And a string which should contain the inner string

```
data{
    // string goes here
}

```

I cannot tab the inner string when I create it. So, my thought was to use `dedent` with Python3 triple-quoted fstrings:

```
import textwrap

inner_str = textwrap.dedent(
    '''\
    This is some text
    across multiple
    lines.'''
)

full_str = textwrap.dedent(
    f'''\
    data{{
        // This should all be tabbed
        {inner_str}
    }}'''
)

print(full_str)

```

However, the indentation is not maintained:

```
    data{
        // This should all be tabbed
        This is some text
across multiple
lines.
    }

```

The desired result:

```
data{
    // This should all be tabbed
    This is some text
    across multiple
    lines.
}

```

How can I preserve the indentation of the fstring without pre-tabbing the inner string?
