將函數結果作爲輸入參數傳遞給類中的函數

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 

如何將x傳遞給func1()？

我已經試過

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

引發我一個錯誤func1() takes exactly 1 argument (2 given)

Answer 1

這應該給你你想要的輸出。您必須將self添加到課程中的每個功能。

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
