why we bother with '{variable}'.format(variable=variable) ?
can we just '{variable}.format()' ?

variable = "Hello, World!"

print('{variable}'.format_map(locals()))

if variable is exist, then assign it.
if variable is not exist, then raise error

I am not language expert. so sorry if this is not a good idea, or already discussed.

As Dustin said, Explicit is Better Than Implicit; you don't want a variable to accidentally make your string formatting work by luck because you forgot to pass in an argument you meant to but just so happened to have a variable with the "right" name.
