Jan 22, 2023

#### Exercise 213

Write a python program that determines the set of prime numbers from 1 to 100.

#### Solution

``#function that tests the primality of a numberdef testPrim(n):     # initialization of the number of divisors of n     numberDiv = 0     for i in range(1,n+1):         # if i is a divisor of n we increment the number of divisors         if n%i == 0:             numberDiv = numberDiv + 1     # number n is prime if and only if numberDiv == 2     if numberDiv == 2:         return True     else:         return False    # initialization of the set of prime numbers from 1 to 100A = set({})# iterate through the set of integers from 1 to 100for i in range(1 , 101):     if testPrim(i):         A.add(i)        # display the set of prime numbersprint("A = ", A)"""output:A = {2, 3, 5, 7, 11, 13, 17, 19, 23,       29, 31, 37, 41, 43, 47, 53, 59,       61, 67, 71, 73, 79, 83, 89, 97}"""``
