识别匹配的类变量并返回变量名

Question

如果我想使用一个函数来识别一个类变量列表是否包含在一个字符串或变量中，我将如何识别文本匹配的特定变量。

class numbersChecks:
    number1 = "123"
    number2 = "456"
    number3 = "789"
    numberCheck = [number1, number2, number3]

sample = "63D456DF1"

def main():
    for i in numbersChecks.numberCheck:
        if i in sample:
            print(i)


if __name__ == '__main__':
    main()

所以在这个例子中，我可以取回456，但是如何取回实际的变量名，比如“number2”

我实际处理的数据是非常非常长的十六进制字符串，所以我尽量避免将长字符串复制到一个单独的字典中，例如{number1:123, number2:456}

Answer 1

您可以按索引或字典：

numbers_to_check = ['123', '456', '789']
for index, number in enumerate(numbers_to_check):
    if number in sample:
        print(index)

或

numbers_to_check = {'number1': '123', 'number2': '456', 'number3': '789'}
for key, number in numbers_to_check.items():
    if number in sample:
        print(key)

第三种方法是使用枚举：

from enum import Enum

class Numbers(Enum):
    number1 = "123"
    number2 = "456"
    number3 = "789"

for number in Numbers:
    if number.value in sample:
        print(number.name)
