Pytype checker funtion

Question

Can you explain what pytype checker does?

Answer 1

Pytype checks and infers types for your Python code without using any type annotations. It can:

• flag common mistakes such as mispelled attribute names, incorrect function calls, and much more, even across file boundaries.
• Enforce user-provided type annotations. 
• Generate type annotations in standalone files ("pyi files"), which can be merged back into the Python source with a provided merge-pyi tool.

Pytype is a static analyzer, which means it does not execute the code it runs on.
