Custom Exception Class in Python
Custom Exception Class for Temperature Control: Write a custom Exception class, derived from the base Exception class, having the following responsibilities. It must take a string argument to display a user-friendly message ("Temperature greater than 400 degrees!!! CODE GREEN! CODE GREEN!") to be displayed when it is raised. It should be raised when the temperature in some system, say, a thermal power plant, crosses 400 degrees Celsius.

class TemperatureError(Exception): pass
myCustomExceptionObject = TemperatureError("Temperature greater than 400 degrees!!! CODE GREEN! CODE GREEN!")
def check_temperature(temperature):
if temperature > 400:
raise myCustomExceptionObject
print("Temperature under control.")
check_temperature(399) # 'Temperature under control.'
check_temperature(450) # amidst stacktrace: 'TemperatureError: Temperature greater than 400 degrees!!! CODE GREEN! CODE GREEN!'
