CSc 120: Classes: Temperatures

Expected Behavior

Attributes:

• _temp: the numerical value of the temperature the object represents;
• _unit: "C" if the object was created using a Celsius temperature; "F" if it was created using a Fahrenheit temperature.

Methods:

• __init__(self, temp, unit): where temp is a number and unit is either "C" or "F" depending on whether temp represents a Celsius or Fahrenheit temperature. This method initializes the _temp attribute of the object with the value of temp and the _unit attribute with the value of unit.

• __str__(self): returns a string consisting of the value of the object's _temp attribute together with the unit ("C" or "F") the object was created with.

• Methods that take a second Temp object other as argument and compare the temperature represented by the object is hotter, cooler, or the same as that represented by other.

  Given two Temp objects t1 and t2, it should be possible to determine relationship between them, i.e., whether they represent the same temperature, or whether one is a bigger or smaller temperature when converted to the same unit, using the comparison operations <, ≤, >, ≥, ==, !=.

Examples

1. t1 = Temp(0, "C")
   t2 = Temp(32, "F")
   t1 == t2
   
   Result: True

2. t1 = Temp(0, "C")
   t2 = Temp(0, "F")
   t1 > t2
   
   Result: True

3. t1 = Temp(100, "C")
   t2 = Temp(212, "F")
   t1 != t2
   
   Result: False

4. t1 = Temp(100, "C")
   str(t1)
   
   Result: '100C'
