Help in writing a simple python program?

. A prime number is a natural number greater than 1 that is not a product of two smaller natural numbers. For example, the first three prime numbers are 2, 3 and 5. Write a function named allPrimes (n) that accepts an Integer (n) as an argument The allPrimes (n) function should use a while loop to create a List containing all the prime numbers less than or equal to (n) Finally, allPrimes (n) will return the List containing the prime numbers . Examples of the allPrimes () function: >>> allPrimes (12) [2, 3, 4, 5, 7, 11] >>> allPrimes (23) [2, 3, 4, 5, 7, 11, 13, 17, 19, 23] >>> allPrimes (5) [2, 3, 4, 5] >>> allPrimes (50) [2, 3, 4, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47]
