For our lab this week, we will write a version of the word guessing game “Hangman.” For those who haven’t played it before you can find many versions of it online or you can read more about it on Wikipedia.
iterableRecall from class that the set class has two “constructors”:
set() -> new empty set
object set(iterable) -> new set object
that is, two ways for creating new set objects. The first is used to create a new empty set. The second we’ve used with lists and strings to create new sets with some initial values.
The definition for this second constructor says that it takes as a
parameter an object that is iterable. iterable classes/objects
provide a common interface to iterate over their elements, independent
of how those elements are organized. For example, we can iterate over
the items in an iterable object using a for loop:
for item in data:
print(item)
data could be any iterable value. Strings, lists and sets are all
iterable, so can be used as the loop sequence (try it out).
Similarly, since the second constructor to set takes something that is
iterable we could use any of these to create a new set as well. This
should explain why when we create a set from a string, as in
set("abcd"), we get a set consisting of the four characters in the
string and not the string itself.
Once you’re comfortable with this idea, write a function called
iterable_to_string that takes a single parameter, an iterable object, and
returns a string consisting of each item in the iterable object converted to
a string using str() and concatenated together, separated by a space. For
example, here are a few calls to this function:
>>> iterable_to_string("abcd")
'a b c d '
>>> iterable_to_string([4, 3, 2, 1])
'4 3 2 1 '
>>> iterable_to_string(set([4, 3, 2, 1]))
'1 2 3 4 '
Notice that all of the strings returned actually have a space at the end as well. Your function doesn’t have to do this, however, it’s fine if it does (an easy way to implement this function results in that behavior).
Submit your function as a Python file named prelab6.py to Gradescope as you would for a lab. You can submit multiple times, with only the most recent submission (before the due date) graded. Note that the tests performed by Gradescope are limited. Passing all of the visible tests does not guarantee that your submission correctly satisfies all of the requirements of the assignment.
