Until recently, I thought python docstrings were just an alternative way to write comments in the code. As I have since learnt, they can be quite useful in writing documentation right into the code. Here's what I mean:
# hello.py
class Hello:
def __init__(self):
"""This is the Hello class init method. It doesn't really
do anything in this code. I just included it here so I can write this
long multi-line docstring."""
pass
def hello():
'Simply prints hello world!'
print("Hello World!")
Above is a simple python script - hello.py
. To see the documentation for that class, run the script in the interactive shell:
$ python3 -i hello.py
>>>
Then, type help(Hello)
:
>>> help(Hello)
A neatly formatted documentation for the class should be returned.
class Hello(builtins.object)
| Methods defined here:
|
| __init__(self)
| This is the Hello class init method. It doesn't really
| do anything in this code. I just included it here so I can write this
| long multi-line docstring.
|
| hello()
| Simply prints hello world!
