我没有错误,但是也没有输出?

有人可以告诉我我在做什么错吗?

我认为问题是事实的数目,可能是我做错了什么?

class weather():
numberOfFacts = 0
count = 0
facts = ''
def __init__(self, FACTS, addFACTS, countFACTS, printFACTS, infer):
   self.FACTS == FACTS
   self.addFACTS == addFACTS
   self.countFACTS == countFACTS
   self.printFACTS == printFACTS
   self.infer == infer

  FACTS.sunIsShining = False;
   FACTS.weatherIsHot = False;
   FACTS.weatherIsCold = False;
   FACTS.wearSunGlasses = False;
   FACTS.summerTime = False;
   FACTS.winterTime = False;
   FACTS.darkClouds = False;
   FACTS.itsRaining = False;
   FACTS.openUmbrella = False;
   FACTS.wearCoat = False;

for fact in f:
     if (FACTS([fact])) ++ 1:
         return count

         for fact in f:

           print("<p>" + fact + "is" + FACT[facts] + "<p>")



   numberOfFacts == countFACTS
     if FACTS.winterTime and FACTS.wearCoat == True: print(FACTS.wearCoat == False)
     if FACTS.weatherIsCold and FACTS.winterTime == True: print(FACTS.summerTime == True)
     if FACTS.itsRaining and FACTS.darkCloud == True: print(FACTS.sunIsShining == False)
     if (FACTS.sunIsShining & FACTS.summerTime) and FACTS.wearSunGlasses == True: print(FACTS.wearSunGlasses == False)
     if FACTS.itsRaining and FACTS.openUmbrella == True: print(FACTS.openUmbrella == False)
     if (FACTS.sunIsShining & FACTS.winterTime) == True: print(FACTS.wearSunGlasses == False, FACTS.darkClouds == False)
     if FACTS.summerTime and FACTS.weatherIsHot == True: print(FACTS.weatherIsHot == False)
     return

答案 0 :(得分:0)

T VonB。=是赋值运算符(您要使用的那个)。您正在使用==,相等比较。您不是在 init ()函数的开头分配值,而是在比较它们。

编辑:(1)为什么在Python中使用分号

(2)您从未在for循环中定义“ f”。

(3)您要在 init

中返回None以外的内容
