‘否则’列表推导式中的语句
我有一个变量，可以是字符串或元组（我提前不知道），我需要将其作为列表使用。
本质上，我想将以下内容转换为列表理解。
variable = 'id'
final = []
if isinstance(variable, str):
final.append(variable)
elif isinstance(variable, tuple):
final = list(variable)
我正在思考以下内容（这给了我一个语法错误）。
final = [var for var in variable if isinstance(variable, tuple) else variable]
我见过这个问题但它不一样，因为提问者可以在最后使用 for 循环；我的仅适用于元组。
注意：如果我使用 isinstance(variable, list) 以及 tuple ，我希望列表理解能够工作。
I've got a variable that could either be a string or a tuple (I don't know ahead of time) and I need to work with it as a list.
Essentially, I want to transform the following into a list comprehension.
variable = 'id'
final = []
if isinstance(variable, str):
final.append(variable)
elif isinstance(variable, tuple):
final = list(variable)
I was thinking something along the lines of the following (which gives me a syntax error).
final = [var for var in variable if isinstance(variable, tuple) else variable]
I've seen this question but it's not the same because the asker could use the for loop at the end; mine only applies if it's a tuple.
NOTE: I would like the list comprehension to work if I use isinstance(variable, list) as well as the tuple one.

我想你想要：
I think you want:
您只需要稍微重新安排一下即可。
或者也许我误解了而你真的想要
You just need to rearrange it a bit.
Or maybe I misunderstood and you really want
