Next, we want to teach our censored calculator to check if numbers are primes or not. This crazy calculator has learned new some words (but forgotten some others) and does not accept new words, certain symbols and it hates digits!

The list of forbidden words and symbols:

  • import
  • div
  • eval
  • range
  • len
  • ⁄ % −
  • digits (0-9)

Given a number (0 < n < 10000),...

Output: Is it prime or not as a boolean.

Example:

checkio(5) == True
checkio(18) == False
    

How it is used: Challenge your creativity and come up with a solution to fit this mission's specs!

Precondition: 1 < number < 10000
