17.5. Improving our Constructor¶
Our constructor so far can only create points at location (0,0)
. To create a point at position (7, 6) requires that we
provide some additional capability for the user to pass information to the constructor. Since constructors are simply specially named functions, we can use parameters (as we’ve seen before) to provide the specific information.
We can make our class constructor more general by putting extra parameters into
the __init__
method, as shown in this codelens example.

Before you keep reading...
Runestone Academy can only continue if we get support from individuals like you. As a student you are well aware of the high cost of textbooks. Our mission is to provide great books to you for free, but we ask that you consider a $10 donation, more if you can or less if $10 is a burden.
Now when we create new points, we supply the x and y coordinates as parameters. When the point is created, the values of initX
and initY
are assigned to the state of the object.
