Distance class

• Read the guideline before start
• Follow Python magic methods if you stuck

Every day you have morning running. You want to store your result. For easier calculating, comparison and printing your result write class Distance.

Distance's __init__ method takes only one argument km and saves it to self.km.

For Distance class you should implement such magic methods:

__init__
distance = Distance(20)  # distance.km == 20

__str__
distance = Distance(20)
print(distance)  # "Distance: 20 kilometers."

__repr__
distance = Distance(20)
repr(distance)  # "Distance(km=20)"

__add__
distance1 = Distance(20)
distance2 = Distance(30)
distance3 = distance1 + distance2  

# isinstance(distance3, Distance) is True
# distance3.km == 50

distance1 = Distance(20)
distance2 = distance1 + 10

# isinstance(distance2, Distance) is True
# distance2.km == 30
# both variants ^ are possible

__iadd__
distance1 = Distance(20)
distance2 = Distance(30)
distance1 += distance2  # distance1.km is 50

distance = Distance(20)
distance += 30  # distance.km == 50

__mul__
distance1 = Distance(20)
distance2 = distance1 * 5  

# isinstance(distance2, Distance) is True
# distance2.km == 100

__truediv__
distance1 = Distance(20)
distance2 = distance1 / 7  

# isinstance(distance2, Distance) is True
# distance2.km == 2.85
# Note: rounded to 2 decimals

__lt__, __gt__, __eq__, __le__, __ge__
distance = Distance(50)
distance < Distance(60)  # True  # distance.km < 60 == True
distance > Distance(120)  # False
distance == Distance(100)  # False
distance <= Distance(49)  # False
distance >= Distance(50)  # True

distance < 60  # True  # distance.km < 60 == True
distance > 120  # False
distance == 100  # False
distance <= 49  # False
distance >= 50  # True
