Exercise: Fahrenheit
Write a function to_fahrenheit(celsius) that returns the temperature celsius in degrees Fahrenheit. Degrees Celsius convert to them by the formula F = C * 1.8 + 32.
to_fahrenheit(100)→212.0to_fahrenheit(-40)→-40.0to_fahrenheit(36.6)→97.88
Constraints: celsius is an int or a float not below absolute zero (−273.15 °C). The result is compared with the expected one approximately: the last digits of fractional numbers may differ. In the tests the helper close does this: its check isinstance(got, (int, float)) accepts both int and float.
Do not add extra imports unless the task says so explicitly.
