I've been assig to do the class rectangle, the class has two instance variables: length and width of the rectangle, and the methods methods setLength(), getLength(), setWidth(), getWidth() and computeArea(). Do you have any idea to do this. Anyway i'm to to python.

Start by declaring a class named Rectangle. Write a constructor (an __init__() method) that accepts arguments self, length and width, and assign the latter two to self.length and self.width inside the constructor.

This basic class example should send you on your Python way:

class Rectangle:
    # class constructor
    # supply it with initial length and width values
    # self refers to the instance
    def __init__(self, length, width):
        self.width = width
        self.length = length

    def setLength(self, length):
        self.length = length

    def show(self):
        print("rectangle has length = {}".format(self.length))
        print("rectangle has width = {}".format(self.width))

length = 10
width = 5
# create a class instance
rect = Rectangle(length, width)

# show initial setting

''' result >>
rectangle has length = 10
rectangle has width = 5

print('-'*40)  # a line of  dashes
# now set length to another value

# show new setting

''' result >>
rectangle has length = 17
rectangle has width = 5
