ValueError：需要解壓縮的值太多（預計爲2）PYTHON

Question

class Strength(State): 
    def run(self, gamedata): 
     print("You have 100 points to assign to your character.\n Start now to assign those Points to your characters strength, agility, speed and defense.") 
     strenghtwert = int(input("STRENGTH: >>")) 
     return AGILITY, gamedata, strenghtwert 

    def next(self, next_state): 
     if next_state == AGILITY: 
      return CreatePlayer.agility 

class Agility(State): 
    def run(self, gamedata,strenghtwert): 
     agilitywert = int(input("AGILITY: >>")) 
     return SPEED, gamedata, strenghtwert, agilitywert 

    def next(self, next_state): 
     if next_state == SPEED: 
      return CreatePlayer.speed 

當我執行此操作時，出現錯誤：ValueError: too many values to unpack (expected 2)。 我認爲錯誤在return AGILITY, gamedata, strenghtwert的run()類Strength。

任何想法是什麼問題？

最後一行成功執行的代碼是strenghtwert = int(input("STRENGTH: >>"))。

沒有更多的信息，如調用的方式，某些變量的類型，錯誤的堆棧跟蹤或完整的代碼。

此錯誤通常發生在多次賦值過程中，您沒有足夠的對象分配給變量，或者您有更多的對象要分配給變量。

例如，如果myfunction（）返回一個帶有三個項目的迭代而不是預期的兩個，那麼您將擁有比指定給變量所需的變量更多的對象。

def myfunction(): 
    return 'stuff', 'and', 'junk' 

stuff, junk = myfunction() 

Traceback (most recent call last): File "/test.py", line 72, in <module> stuff, junk = myfunction() ValueError: too many values to unpack (expected 2)

它解決，你必須比對象更多的變量的其他方式。

def myfunction(): 
    return 'stuff' 

stuff, junk = myfunction() 

Traceback (most recent call last): File "/test.py", line 72, in <module> stuff, junk = myfunction() ValueError: too many values to unpack (expected 2)
