Is it possible to use static typing in Python? For example if I declare a variable of type int and then I assign the value 'one' no error occurs, I wonder if there is any way to prevent this kind of thing.

x: int

x = 'um'

  • Buddy, you know that x:int is a note right?

  • Yes but I want to know if it has how to use to type a variable.

  • It’s just an annotation, python won’t stop you from passing a string or a list in x for example, but the IDE will issue a Warning saying that it has an annotation saying that it is int and vc is passing a string. Doc: https://docs.python.org/3/library/typing.html

Directly in standard Python has no way, only can give the hint same. You can make a static analysis tool that checks the code and reports an error when you try to assign an invalid value to an annotated variable with a certain type. I may even have a tool ready from someone who does this, but I don’t know. Otherwise it has Python dialects with even static typing, for example Cython or Mypy.
