如何检查一个变量是否存在于多个列表中？

这是我的代码的摘录！

division = ["Division","Divide","/","div"]
multiplication =["*","x","times","multiply","multiplication","multiple"]
subtraction = ["-",'minus','subtract','subtraction']
addition = ['+','plus','addition','add']
root = ['root','squareroot','square root']
square = ['square','squared','power 2']

choice = input('calculation type')
print(choice == (division or multiplication or subtraction or addition))

到目前为止，它只给出“False”。 如何检查一个变量是否存在于多个列表中？ 我尝试在列表中创建列表，但仍然得到“False”，这是代码......

division = ["Division","Divide","/","div"]
multiplication = ["*","x","times","multiply","multiplication","multiple"]
subtraction = ["-",'minus','subtract','subtraction']
addition = ['+','plus','addition','add']
root = ['root','squareroot','square root']
square = ['square','squared','power 2']
basic_double = [division,multiplication,subtraction,addition]
basic_single = [root,square]
choice = input('calculation type')
print(choice == basic_double or basic_single)

任何帮助，将不胜感激！ ：谢谢！

测试是否choice is in any列表中：

any(choice in ls for ls in [division, multiplication, subtraction, addition])

any如果给定可迭代对象的至少一个元素为真，则返回 True。

choice in ls测试 choice 是否是列表的元素。

choice in ls for ls in [division, multiplication, subtraction, addition]是一个生成器理解，意味着它是一个返回结果的迭代器choice in ls对于任何可能的ls in [division, multiplication, subtraction, addition].

If one这些列表包含choice, any将返回 True，否则返回 False。
