numpy has a lot of functions in it, so we’ve narrowed it down to four possible functions that could be numpy.histogram() in disguise: numpy.leyud(), numpy.uqka(), numpy.fywdkxa() or numpy.jinzyxq().Įxamine each of these functions’ docstrings in the IPython shell to determine which of them is actually numpy.histogram().

Fortunately for you, the maniac didn’t think to alter the docstrings, and you know how to access them. You desperately need to call the numpy.histogram() function and you don’t have time to reinstall the package. Some maniac has corrupted your installation of numpy! All of the functions still exist, but they’ve been given random names. But when we want to print the docstring, removing those leading spaces with inspect.getdoc() will look much better.

That’s because the docstring is indented to line up visually when reading the code. This IDE is going to be an incredibly delightful experience for your users now! Notice how the count_letter._doc_ version of the docstring had strange whitespace at the beginning of all but the first line. Sep: string inserted between values, default a space.Įnd: string appended after the last value, default a newline.įlush: whether to forcibly flush the stream. Prints the values to a stream, or to sys.stdout by default.įile: a file-like object (stream) defaults to the current sys.stdout. , sep=' ', end=' ', file=sys.stdout, flush=False) When step is given, it specifies the increment (or decrement).

These are exactly the valid indices for a list of 4 elements. Start defaults to 0, and stop is omitted! range(4) produces 0, 1, 2, 3. Return an object that produces a sequence of integers from start (inclusive) Use an attribute of the count_letter() function.Ĭount the number of times `letter` appears in `content`.

Begin by getting the docstring for the function count_letter().

You will be reusing the count_letter() function that you developed in the last exercise to show that we can properly extract its docstring. You’ve been asked to complete the build_tooltip() function that retrieves a docstring from an arbitrary function. That way, the user doesn’t have to go elsewhere to look up the documentation for the function they are trying to use. The team wants to add a feature that displays a tooltip with a function’s docstring whenever the user starts typing the function name. You and a group of friends are working on building an amazing new Python IDE (integrated development environment - like P圜harm, Spyder, Eclipse, Visual Studio, etc.).

Remember that even though computers execute it, code is actually written for humans to read (otherwise you’d just be writing the 1s and 0s that the computer operates on). While it does require a bit more typing, the information presented here will make it very easy for others to use this code in the future. Raise ValueError('`letter` must be a single character string.') If (not isinstance(letter, str)) or len(letter) != 1: ValueError: If `letter` is not a one-character string. # Add a section detailing what errors might be raised

'''Count the number of times `letter` appears in `content`. Finally, add some information about the ValueError that gets raised when the arguments aren’t correct.Add a returns section that informs the user the return value is an int.Now add the arguments section, using the Google style for docstrings.Copy the following string and add it as the docstring for the function: Count the number of times `letter` appears in `content`.Build up a Google Style docstring for this function by following these steps. You want the users of your open-source package to be able to understand how this function works easily, so you will need to give it a docstring. It takes a string and a single letter and returns the number of times the letter appears in the string. The first function you write is count_letter(). It will revolutionize working with free-form text, the way numpy did for arrays, pandas did for tabular data, and scikit-learn did for machine learning. You’ve decided to write the world’s greatest open-source natural language processing Python package. Posted On 6 October 2021 Crafting a docstring
