DocStrings provide a convenient way of associating documentation with Python code. They help developers understand the purpose and usage of the code without reading through the implementation. You can use the help() function to access the docstring of an object.
DocStrings
help()
DocStrings, or documentation strings, are a special kind of comment used to describe what a function, method, class, or module does. They are written inside triple quotes (""" or ''') and are placed immediately after the definition of a function, method, class, or module.
"""
'''
Here’s an example of a simple function with a DocString:
def greet(name): """ This function greets the person whose name is passed as a parameter. Parameters: name (str): The name of the person to greet. Returns: str: A greeting message. """ return f"Hello, {name}!"
In this example, the DocString explains what the greet function does, describes its parameter, and mentions the return value.
greet
You can access the DocString of a function, method, class, or module using the help() function or the __doc__ attribute.
__doc__
The help() function displays the DocString and other relevant information about an object.
def greet(name): """ This function greets the person whose name is passed as a parameter. Parameters: name (str): The name of the person to greet. Returns: str: A greeting message. """ return f"Hello, {name}!" help(greet)
When you run this code, it will display the DocString for the greet function.
You can also access the DocString directly using the __doc__ attribute of the object.
print(greet.__doc__)
This will print the DocString of the greet function.
class Robot: """ A class to represent a robot. Attributes: name (str): The name of the robot. speed (int): The speed of the robot. Methods: greet(): Greets the user. set_speed(speed): Sets the speed of the robot. """ def __init__(self, name, speed=0): """ Constructs all the necessary attributes for the robot object. Parameters: name (str): The name of the robot. speed (int): The speed of the robot. """ self.name = name self.speed = speed def greet(self): """ Greets the user by printing a greeting message. """ print(f"Hello, I am {self.name}") def set_speed(self, speed): """ Sets the speed of the robot. Parameters: speed (int): The new speed of the robot. """ self.speed = speed
In this example, the Robot class is well-documented with DocStrings for the class itself, the __init__ method, and other methods.

DocStrings in MicroPython provide a way to document your code, making it easier to understand and use. By following best practices for writing DocStrings, you can ensure that your code is well-documented and accessible to other developers.
