我很抱歉问一个非常简单的问题，但是我需要解决它才能正确执行我的个人Python代码。
下面的代码是一个计算器，可以计算加减乘除法并保存过去 10 次计算中的所有结果，如果计算次数超过 10 次，则再次保存到第一个计算中。
但是当我运行此代码时，错误NameError: name 'counter' is not defined出现。
我希望任何解决方案都能解决此定义变量，因为即使我正在定义"计数器"，也会发生此错误。

看起来有些代码需要缩进更多。
取而代之的是...
def processes(decision, counter):
decision = decideprocess()
if decision == "+":
addition(counter)
decideprocess()
return counter
elif decision == "-":
subtraction(counter)
decideprocess()
return counter
elif decision == "*":
multiplecation(counter)
decideprocess()
return counter
elif decision == "/":
devision(counter)
decideprocess()
return counter
elif decision == "all":
print(answer0)
print(answer1)
print(answer2)
print(answer3)
print(answer4)
print(answer5)
print(answer6)
print(answer7)
print(answer8)
print(answer9)
decideprocess()
return answe1, answer2, answer3, answer4, answer5, answer6, answer7, answer8, answer9, answer10, counter, decision, result
。试试这个：
def processes(decision, counter):
decision = decideprocess()
if decision == "+":
addition(counter)
decideprocess()
return counter
elif decision == "-":
subtraction(counter)
decideprocess()
return counter
elif decision == "*":
multiplecation(counter)
decideprocess()
return counter
elif decision == "/":
devision(counter)
decideprocess()
return counter
elif decision == "all":
print(answer0)
print(answer1)
print(answer2)
print(answer3)
print(answer4)
print(answer5)
print(answer6)
print(answer7)
print(answer8)
print(answer9)
decideprocess()
return answe1, answer2, answer3, answer4, answer5, answer6, answer7, answer8, answer9, answer10, counter, decision, result
