An appropriate Docstring for your hello() function is ‘Prints “Hello World”’. def hello(): """Prints "Hello World". Returns: None """ print("Hello World") return Note that docstrings can be more prolonged than the one that is given here as an example. If you’d like to study...
The first line of a documentation string can be indented up to three spaces but must be preceded by a blank line. The rest of the docstring may be indented any amount you like. defgreet(name):""" This is a docstring. It provides documentation for the greet function. The function takes...
Godoc is conceptually related to Python’s Docstring and Java’s Javadoc but its design is simpler. The comments read by godoc are not language constructs (as with Docstring) nor must they have their own machine-readable syntax (as with Javadoc). Godoc comments are just good comments, the ...
If you haven’t added any extra options on top of the field you inherited from, then there’s no need to write a newdeconstruct()method. If, however, you’re changing the arguments passed in__init__()(like we are inHandField), you’ll need to supplement the values being passed. ...
You could not write similar code in a Python module. Consider the _ in the interpreter as a side effect that you took advantage of. In a Python module, you would assign a name to the lambda, or you would pass the lambda to a function. You’ll use those two approaches later in this...
Write Docstrings:Document the expected parameter types and return types/values in the function's docstring. Add Unit Tests:Create tests that specifically check the function's return type under various input conditions. (See the function example in the "Common Scenarios" section for code demonstrating...
or nosetests won’t pick it up. Now is a good time to add your test’s docstring. The docstring should include a description of what your test is trying to verify and how, as well as somedoxygen markup. See dtest’scontributing.mdfor more on the appropriate doxygen annotations to use....

In this code, you first set the value of num to 10 and then tried to write the if statement without indentation. In fact, the IPython console is smart and automatically indents the line after the if statement for you, so you’ll have to delete the indentation to produce this error. Whe...
You can write one-line docstrings or multi-line docstrings. One-line docstrings are suitable for simple code that doesn’t require a lot of documentation. Below is an example of a function called multiply. The docstring explains the multiply function takes two numbers, multiples them, and ...
