Rete模式匹配算法没有输出，但也没有错误？

Question

我没有错误，但也没有输出？

有人能告诉我我哪里做错了吗？

我认为问题出在numberofFacts上，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

T Von B. =是您正在使用的==的赋值运算符(您想要使用的运算符)，即相等比较。不是将值赋给init()函数开头的值，而是对它们进行比较。

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)在初始化中，您返回的不是None
