When you run mypy on your Python file, it prints out the inferred type from the script’s reveal_type() function. In this example, mypy correctly infers that the result variable is a tuple containing two strings or an empty value of None. Remember that IDEs and third-party static type ...
The first two invocations will work because we're passing arguments that belong to theTypeVarset of types, and the function will behave accordingly since both types implement the+operation. It will actually run for the third invocation because Python has this same operation for strings. Still, my...
We present 位 re , a minimal functional calculus with regular expression types for strings, in order to establish a theoretical foundation of using regular expressions as types of strings in text processing languages. The major technical novelties in this paper (with respect to other work such as...
