input: Write a function to check if a number is prime and print all prime numbers between 0 and 100.
  assert isPrime(2) == True
  assert isPrime(4) == False
  assert isPrime(97) == True
output: def isPrime(n):
      if n <= 1:
          return False
      for i in range(2, int(n**0.5) + 1):
          if n % i == 0:
              return False
      return True
  
  for num in range(101):
      if isPrime(num):
          print(num)
