# Basic method of setting and getting attributes in Python
class Celsius:
def __init__(self, temperature=0):
self.temperature = temperature
def to_fahrenheit(self):
return (self.temperature * 1.8) + 32
# Create a new object
human = Celsius()
# Set the temperature
human.temperature = 37
# Get the temperature attribute
print(human.temperature)
# Get the to_fahrenheit method
print(human.to_fahrenheit())
Thank you!

# Making Getters and Setter methods
class Celsius:
def __init__(self, temperature=0):
self.set_temperature(temperature)
def to_fahrenheit(self):
return (self.get_temperature() * 1.8) + 32
# getter method
def get_temperature(self):
return self._temperature
# setter method
def set_temperature(self, value):
if value < -273.15:
raise ValueError("Temperature below -273.15 is not possible.")
self._temperature = value
# Create a new object, set_temperature() internally called by __init__
human = Celsius(37)
# Get the temperature attribute via a getter
print(human.get_temperature())
# Get the to_fahrenheit method, get_temperature() called by the method itself
print(human.to_fahrenheit())
# new constraint implementation
human.set_temperature(-300)
# Get the to_fahreheit method
print(human.to_fahrenheit())
Thank you!
