I have to write a function which looks like the following: def funci(x1, ..., xki) -> y1,...,ymi, where all x's and y's have type TypeClass. Using typing module, I could declare the function as: f(*args: TypeClass), but how to define the type of the variable-length returned values?

CodePudding user response：

From the typing documentation,

To specify a variable-length tuple of homogeneous type, use literal ellipsis, e.g. Tuple[int, ...].

In your case, the return type should be Tuple[TypeClass, ...].
