input: Write a Python function to convert a list of values from Celsius to Fahrenheit.
  assert celsiusToFahrenheit([0, 10, 20]) == [32.0, 50.0, 68.0]
  assert celsiusToFahrenheit([-40, 0, 100]) == [-40.0, 32.0, 212.0]
  assert celsiusToFahrenheit([30, -10, 15]) == [86.0, 14.0, 59.0]
output: def celsiusToFahrenheit(celsius_list):
      return [(c * 9/5) + 32 for c in celsius_list]
