def bmicalculation(self):
        bmiheight=self.heightcm.get()
        print(bmiheight)
        bmiweight=self.weightkg.get()
        bmi= float((bmiweight)/((bmiheight / 100)**2))
        print(bmi)
        self.label1=Label(self.master,text='Your BMI is %.2f' % bmi).grid(row=5,column=0)

        if bmi <= 18.5:
            self.label2=Label(self.master,text='This places you in the underweight group.',fg='blue').grid(row=6,column=0)
            totalindex = 'underweight'
        elif bmi >18.5 and bmi <25:
            self.label3=Label(self.master,text='This places you in the healthy weight group.',fg='green').grid(row=6,column=0)
            totalindex = 'healthy'
        elif bmi >= 25 and bmi < 30:
            self.label4=Label(self.master,text='This places you in the overweight group.',fg='orange').grid(row=6,column=0)
            totalindex = 'overweight'
        elif bmi >=30:
            self.label5=Label(self.master,text='This places you in the obese group.',fg='red').grid(row=6,column=0)
            totalindex = 'obese'

        if bmi >0 and bmi <999999999999999999999:
            self.button6=Button(self.master,text="Store Data",fg='red',command=self.dynamic_data_entry).grid(row=8,column=0)


    def dynamic_data_entry(self):
        #this is what adds the data to the database. Bmi has to be changed to the value of bmi and weightclass has to be change to the weightclass
        timestamp = str(datetime.datetime.now().date())
        bodymassindex = '20'
        weightclass = str(totalindex)
        c.execute("INSERT INTO BMIStorage (timestamp, bodymassindex, weightclass) VALUES (?, ?, ?)",(timestamp, bodymassindex, weightclass))
        conn.commit()

我想在我的第二个定义bmi中回顾我创建的def dynamic_data_entry这个词。我怎么能这样做？

另外，我怎样才能将BMI给出的权重组转换为一个字符串，然后我可以将其放入由SQLite创建的数据库中？

Answer 1

使bmi类变量类似于self.bmi。同样适用于totalindex。

bmi= float((bmiweight)/((bmiheight / 100)**2))
self.bmi = bmi

.

.
elif bmi >=30:
    self.label5=Label(self.master,text='This places you in the obese group.',fg='red').grid(row=6,column=0)
    totalindex = 'obese'

self.totalindex = totalindex

现在，您可以使用self.bmi方法访问self.totalindex和dynamic_data_entry。

Answer 2

如果你的第二个函数def dynamic_data_entry def bmicalculation(self)函数，那么bmi变量应该可以在函数内部访问。

如果不是，则需要将其作为参数传递给def dynamic_data_entry

参考python中的前一个语句
