input: Write a python function to generate a list of random strings of given length and count.
  assert len(generate_list_of_strings(5, 5)) == 5
  assert all(len(s) == 5 for s in generate_list_of_strings(5, 5))
  assert len(generate_list_of_strings(10, 3)) == 3
output: import random
  import string
  
  def generate_list_of_strings(length, count):
      return [''.join(random.choices(string.ascii_letters + string.digits, k=length)) for _ in range(count)]
