input: Write a python function to convert a list of temperatures from Celsius to Fahrenheit.
  assert convert_temps([36.5, 37, 37.5, 38]) == [97.7, 98.6, 99.5, 100.4]
  assert convert_temps([-40, 0, 100]) == [-40.0, 32.0, 212.0]
  assert convert_temps([0, 20, 30, 40]) == [32.0, 68.0, 86.0, 104.0]
output: def convert_temps(celsius_temps):
      return [(temp * 9/5) + 32 for temp in celsius_temps]
