Question

我在一个类中有两个方法。我想在另一个内部调用一个方法的变量。这是我的代码：

＃第一种方法：

def starter_loan_check(self):
    #global total_offer,final_offer
    #final_offer=[]
    for i in self.overall_data:
        if i[1]=='PS' and i[3] in conf.PS_State and i[5]>29:
            if i[2]!='challengerTUFT':
                for c in cutoff_config:
                    if i[3]==c['State'] and i[2]==c['challenger'] and i[4]<['CUTOFF3'] and i[4]>=['CUTOFF4']:
                        if i[7]>50:
                            global total_offer,final_offer
                            final_offer=[]
                            total_offer=[i for i in product(*[conf.i[3]['Loan_Amount'],conf.i[3]['Apr'],conf.i[3]['Term']])
                            #global total_offer,final_offer
                            #final_offer=[]
                            for t in total_offer:
                                if t[0]>min(i[3]['Loan_Amount']) and t[1] in i[3]['Apr'] and t[2] in i[3]['Term']:
                                    final_offer.append(t)
                                elif t[0]>max(i[3]['Loan_Amount']) and t[1] in i[3]['Apr'] and t[2] in i[3]['Term']:
                                    t[0]=max(i[3]['Loan_Amount'])
                                    final_offer.append(t)
                                elif i[9]>75:
                                    if t[0]>min(i[3]['Loan_Amount']) and t[1] in i[3]['Apr'] and t[2] in i[3]['Term']:
                                        final_offer.append(t)
                                    elif t[0]>max(i[3]['Loan_Amount']) and t[1] in i[3]['Apr'] and t[2] in i[3]['Term']:
                                        t[0]=max(i[3]['Loan_Amount'])
                                        final_offer.append(t)

我正在尝试在此处访问final_offer 第二种方法：

def starter_loan_logic(self):
    for i in  self.query1_data:
        for j in final_offer:
            if j[0]/(i[3]*.85)>.30:#LTI Check
                final_offer.remove(j)

            if i[2]==j[0] and i[4]=='BI_WEEKLY':
                PTI=i[5]/((i[3]*0.85)/12)>0.20
                final_offer.remove(j)

            if i[2]==j[0] and i[4]=='TWICE_PER_MONTH':
                PTI=i[6]/((i[3]*0.85)/12)>0.20
                final_offer.remove(j)

            if i[2]==j[0] and i[4]=='MONTHLY':
                PTI=i[7]/((i[3]*0.85)/12)>0.20
                final_offer.remove(j)

            for k in self.overall_data:
                k['state']=='IL' and i[5]/((i[3]*0.85)/12)>0.225
                final_offer.remove(j)

但是我在total_offer中的t处收到无效的语法错误在这里，我尝试了Global，但是不确定是否正确使用了Global。请帮助我了解如何在另一个函数中访问一个函数的变量。

虽然可以使用不是推荐的方法来使用全局变量。

您要做的是将这些变量作为调用者设置的参数传递到函数中。因此第一种方法应类似于：

def starter_loan_check(self, total_offer):
    final_offer = []
    << do loan check loop as above  - but don't initialize final_offer in the loop>>
    return final_offer

第二个循环如下所示：

def starter_loan_logic(self, final_offer):
   <<do you loop here>>

无论何时调用这两个函数，都需要通过以下方式传递变量：

total_offer = <<something>>
final_offer = self.starter_loan_check(total_offer)
self.starter_loan_logic(final_offer)

如何在Python中的另一个方法中调用方法变量
