For checking if a file exists use |filereadable()|.
The {expr} argument is a string, which contains one of these:
varname internal variable (see
dict.key |internal-variables|). Also works
list[i] for |curly-braces-names|, |Dictionary|
import.Func entries, |List| items, imported

Does not work for local variables in a
compiled `:def` function.
Beware that evaluating an index may
cause an error message for an invalid
expression. E.g.: >
:let l = [1, 2, 3]
:echo exists("l[5]")
< 0 >
:echo exists("l[xx]")
< E121: Undefined variable: xx
