刪除函數調用錯誤？

Question

我想編程主謀（遊戲），在我for循環在這一行::

del cpureturn(rndm_cpureturn) 

我不斷收到同樣的錯誤：

SyntaxError: can't delete function call

這是爲什麼發生和我如何解決它？

#Color Database 
colorpegs = ['blue', 'black', 'red', 'white', 'yellow', 'green'] 
correctingpegs = ['White', 'Black'] 

#CPU Code Generator 

code1 = r.choice(colorpegs) 
code2 = r.choice(colorpegs) 
code3 = r.choice(colorpegs) 
code4 = r.choice(colorpegs) 

cpucode = [code1, code2, code3, code4]

     del cpureturn(rndm_cpureturn)

     sys.exit() 


    if guessround == 10: 
     print('You Lose, better luck next time') 
     print('The code was' + cpucode)

    guessround = guessround + 1

貌似要刪除的特定元素（由它的價值，而不是它的位置）cpureturn。要做到這一點，使用remove方法：

cpureturn.remove(rndm_cpureturn) 

注意del作品通過指定索引：

i = r.randrange(len(cpureturn)) # get an index, not a value 
del cpureturn[i]
