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
