input: Write a function that suggests a valid Python syntax to calculate the sum of two variables using a lambda function. The function should accept the two variables as input and print their sum.
  
  assert calculate_sum(3, 4) == "sum = lambda a, b : a + b\nprint(sum(3,4))"
  assert calculate_sum(10, 20) == "sum = lambda a, b : a + b\nprint(sum(10,20))"
  assert calculate_sum(0, 0) == "sum = lambda a, b : a + b\nprint(sum(0,0))"
  assert calculate_sum(-5, 5) == "sum = lambda a, b : a + b\nprint(sum(-5,5))"
  assert calculate_sum(100, -100) == "sum = lambda a, b : a + b\nprint(sum(100,-100))"
output: def calculate_sum(a, b):
      return f"sum = lambda a, b : a + b\nprint(sum({a},{b}))"
