我正在使用以下内容从programa1
为新对象发送变量值:
def send_price(self):
self.pricesend = float(self.text1.get()) #this take a value from a tkinker.Entry
print(self.pricesend)
objetoprograma1.Object(self.pricesend)
对象“objetoprograma1”使用以下命令返回一个新值:
class Object():
def __init__(self, price):
self.price_recibe = float(price)
print(self.price_recibe)
self.new_price = self.price_recibe + 10
print(self.new_price)
programa1.Aplication.recibe_newprice(self, float(self.new_price))
现在我要更新名为principal1
的{{1}} tkinter.Entry
中的值:
self.text1
我有以下例外:
def recibe_newprice(self, new_price):
self.new_price = new_price
print("price new recibe" , self.new_price)
## this don't work.. this don't update or change the value in the tkinter.Entry
self.text1.delete(0, len(self.text1.get()))
self.text1.insert(self.my_main, str(self.new_price))

答案 0 :(得分:0)
查看您的Object类并查看异常消息。您正在调用recibe_newprice
方法,但是将Object
实例传递给它(对象没有text1属性)。 recibe_newprice
是为Aplication
类编写的,因此期望self
成为Aplication
类的实例。您似乎正在混淆类的用途或self
参数的工作原理。
我的第一个提示是用更具描述性的名称命名。 Object
,Application
和Program1
等名称不会告诉读者有关这些对象的用途的信息。
其次,你知道类和函数之间的区别吗?也许这会有所帮助。我会用这种方式编写send_price
方法:
def send_price(self, price_recibe):
pricesend = float(self.text1.get())
print(pricesend)
print(price_recibe)
new_price = price_recibe + 10
print(new_price)
self.recibe_newprice(new_price)
如果这没有意义,为什么我这样做,或为什么这可能比你做的更好/更容易,那么我建议研究如何python类,属性赋值和参数通过工作。
