The notebook currently lacks a section on type hints, which are a significant feature of modern Python programming for static type checking and code clarity.
Proposed Change
Add a new section dedicated to type hints, explaining their purpose and how they can be used in Python code.
Provide practical code examples that demonstrate how to add type hints to functions and variables.
Link to the official Python documentation for a more in-depth explanation.
Example Implementation
## Type Hints in Python
Type hints are a feature in Python that allow you to specify the expected data types of variables, function arguments, and return values. While type hints are not enforced at runtime, they provide developers with a clear contract of what a function expects and returns. They are especially helpful for larger codebases, static type checking, and improving IDE support with autocompletion and linting.
Here's how you can add type hints to your Python code:
### Basic Type Hints```python# Specifying the data type of a variable
age: int=25# Adding type hints to function parameters and return typedefgreet(name: str) -> str:
returnf"Hello, {name}!"
Advanced Type Hints with Collections
fromtypingimportList, Dict# Specifying a list of integersnumbers: List[int] = [1, 2, 3, 4, 5]
# Defining a dictionary with string keys and float valuesprices: Dict[str, float] = {'apple': 0.5, 'banana': 0.75}
Functions with Type Hints
fromtypingimportTuple# A function that returns a tuple of a string and an integerdefget_data() ->Tuple[str, int]:
return"data", 42
More examples
fromtypingimportSet, Tuple# A set of unique stringsusernames: Set[str] = {'user1', 'user2', 'admin'}
# A tuple with mixed data typesperson_info: Tuple[str, int, bool] = ('Alice', 30, True)
