In Python, isdigit() is a string method. It checks if every character is a digit.
In Nim, all() and any() are defined in std/sequtils:
proc all[T](s: openArray[T]; pred: proc (x: T): bool {.closure.}): bool {.effectsOf: pred.}
proc any[T](s: openArray[T]; pred: proc (x: T): bool {.closure.}): bool {.effectsOf: pred.}
all(): Iterates through a container and checks if every item fulfills the predicate.
any(): Iterates through a container and checks if at least one item fulfills the predicate.
