Type hints can be used to communicate the intended type of a given variable. These are not enforced at runtime and not respecting them might not necessarily lead to runtime errors.
It is however confusing and could lead to maintainability issues.
== Noncompliant Code Example
----
def my_function():
my_int: int = "string" # Noncompliant
== Compliant Solution
my_str: str = "string"
