I main java and just started on python, and I ran into this error when I was trying to create a class. Can anyone tell me what is wrong?

import rectangle

a = rectangle(4, 5)

print(a.getArea())

this is what is in the rectangle class:

class rectangle:
    l = 0
    w = 0

    def __init__(self, l, w):
        self.l = l
        self.w = w

    def getArea(self):
        return self.l * self.w

    def getLength(self):
        return self.l

    def getWidth(self):
        return self.w

    def __str__(self):
        return "this is a", self.l, "by", self.w, "rectangle with an area of", self.getArea()

I don't know what you have implemented in the rectangle module but I suspect that what you're actually looking for is this:

from rectangle import rectangle
a = rectangle(4, 5)
print(a.getArea())

If not, give us an indication of what's in rectangle.py

CodePudding user response：

your gonna need to specify what module the function is from so either import all the functions so change import rectangle to from rectangle import *

or switch the rectangle(4,5) to rectangle.rectangle(4,5)
