'calculation parameters in format_map()
I read a formatting message from database, and I want to fill message parameters from a dictionary.
The problem is where I got a mixed parameter that need calculation.
data = {"p1": 10, "p2": 8}
msg = "user point is {p1+p2}" # read from database
print(msg.format_map(data))
How can I handle this?

?? Do not rely on the following if you do not know what 1) “dynamic evaluation” exactly means and 2) what are the exact security risks (e.g. *) you are taking by doing so. ??
>>> eval(f'f"{msg}"', None, data)
'user point is 18'
