This is not what I get:

    Python 3.6.5 (default, May 11 2018, 13:30:17) 
    [GCC 7.3.0] on linux
    Type "help", "copyright", "credits" or "license" for more information.
    >>> k=1
    >>> v=2
    >>> print(f'this is {{k}} and {{v}}')
    this is {k} and {v}
    >>> print(f'this is {k} and {v}')
    this is 1 and 2
    >>> print(f'Email: {d:{{k}} {{v}}}')
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    NameError: name 'd' is not defined
