py-mypy py-mypy_extensions: updated to 1.0.0

Mypy 1.0 Released

Now that mypy reached 1.0, we’ll switch to a new versioning scheme. Mypy \ 
version numbers will be of form x.y.z.

Mypy 1.0 is up to 40% faster than mypy 0.991 when type checking the Dropbox \ 
internal codebase. We also set up a daily job to measure the performance of the \ 
most recent development version of mypy to make it easier to track changes in \ 
performance.

Mypy will now generate an error if you use a variable before it’s defined. \ 
This feature is enabled by default. By default mypy reports an error when it \ 
infers that a variable is always undefined.

A new experimental possibly-undefined error code is now available that will \ 
detect variables that may be undefined.

There is now a simpler syntax for declaring generic self types introduced in PEP \ 
673: the Self type. You no longer have to define a type variable to use “self \ 
types”, and you can use them with attributes.
