Question

我是python的新手，因此在基于类和对象的问题上运行代码时遇到此错误：IndentationError：意外缩进但不知道我哪里出了问题请帮我得到它以及如何解决它感谢你在期待.... 祝你今天愉快！：>

class Get_started:
    def __init__(self,name):
        self.name = str(input('Enter name'))
        print('Hello ',self.name)
        self.rect = self.Rectangle()

    class Rectangle:
    def __init__(self):
        print('In this program we are gonna calculate the area of rectange')

    def get_lb(self,l,b):
        self.l = int(input('Enter length  : '))
        self.b = int(input('Enter breadth : '))

    def show():
        print('Length & Breadth of rectangle are ',self.l,' & ',self.b)
    def cal_area(self):
        self.area = self.l * self.b
            print('Area : ',self.area)

m1 = Get_started('mr_halkat')
m1.Rectangle.get_lb()
m1.Rectangle.show()
m1.Rectangle.cal_area()

Answer 1

您需要缩进Rectangle类中的所有内容，并减少print方法中cal_area语句上的缩进。

这是修改后的代码：

#!/usr/bin/python

class Get_started:
    def __init__(self,name):
        self.name = str(input('Enter name'))
        print('Hello ',self.name)
        self.rect = self.Rectangle()

    class Rectangle:
        def __init__(self):
            print('In this program we are gonna calculate the area of rectange')

        def get_lb(self,l,b):
            self.l = int(input('Enter length  : '))
            self.b = int(input('Enter breadth : '))

        def show():
            print('Length & Breadth of rectangle are ',self.l,' & ',self.b)
        def cal_area(self):
            self.area = self.l * self.b
            print('Area : ',self.area)

m1 = Get_started('mr_halkat')
m1.Rectangle.get_lb()
m1.Rectangle.show()
m1.Rectangle.cal_area()

Answer 2

它说class Rectangle中没有函数，并且cal_area(self)函数中的缩进错误

您是否尝试像这样放置代码：

class Rectangle:
     def __init__(self):
          print('In this program we are gonna calculate the area of rectange')
     def get_lb(self,l,b):
          self.l = int(input('Enter length  : '))
          self.b = int(input('Enter breadth : '))

     def show():
          print('Length & Breadth of rectangle are ',self.l,' & ',self.b)
     def cal_area(self):
          self.area = self.l * self.b
          print('Area : ',self.area)

错误：IndentationError：意外缩进
