类型错误：'list'对象不可调用Python

Question

我创建了一个这样的列表：

symbolList = []

何时

if symbolList(int(individualPassCounter)) == "A":

调用列表，我的脚本停止并给我错误：

TypeError: 'list' object is not callable

如果有人知道为什么答案会受到赞赏。

编辑完整代码：

data = ['a', 'b', 'c', 'd' ,'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z']

        symbolList.append(symbolType)

    else:
        print("\nWrong type selected, try again.")
        symbolType = input("\nInput" + str(symbolAmountCounter+1)+ ". symbol type:\t")
symbolAmountCounter += 1

    for x in passwordListFinished:
        if (x == individualPassword):
            return False

while i < len(passwordListFinished):
    f.write("\n" + passwordListFinished)
    f.close()
    print("Passwords Generated")

Answer 1

变化

if symbolList(int(individualPassCounter)) == "A":

到

if symbolList[int(individualPassCounter)] == "A":

使用方括号访问列表对象，而不是括号。 您还需要处理IndexError异常

Answer 2

Parens用于调用函数。方括号用于访问序列和映射。

somelist[...]
