将函数结果作为输入参数传递给类中的函数

Question

 class main_prg:
      def func():
            # code that generates x and y
            return x,y
      def func1(x):
            #uses the value of x that is returned from func()
           z=x+3
            return z

如何将x传递给func1()

我试过了

m=main_prg()
f01,f11 = m.func()
f2 = m.func1(f01)

向我抛出一个错误func1() takes exactly 1 argument (2 given)

Answer 1

这会给你你想要的输出。必须向类中的每个函数添加self

class main_prg:
      def func(self):
            # code that generates x and y
            x = 1 # whatever
            y = 2 # whatever
            return x,y
      def func1(self, x):
            #uses the value of x that is returned from func()
            z = 3 # whatever
            return z

m = main_prg()
f01,f11 = m.func()
print f01
print f11
f2 = m.func1(f01)
print f2

• f01打印1
  
• f11打印2
  
• f2打印3
