Issue in Part 2 Exercise: Story

[Aadithya369]

For the exercise Story in part 2 it has two parts namely part 1 and part 2 and only 1 code runner provided for both parts.
When testing code for part 1

story = ""
while True:
    word = input("Please type in a word: ")
    if word == "end":
        break
    story += word + " "

print(story)

'hello world' != ''
- hello world
+ 
 : With the input
hello
world world
your program should print out:
hello world
your program printed out:

The testcase does not have the word end so the program actually never halts.

When testing code for part 2

story = ""
while True:
    word = input("Please type in a word: ")
    if word == "end" or word in story:
        break
    story += word + " "

print(story)

'Once upon a time there was a girl' != 'Once upon a time there was'
- Once upon a time there was a girl
?                           -------
+ Once upon a time there was
 : With the input
Once
upon
a
time
there
was
a
girl
end
your program should print out:
Once upon a time there was a girl
your program printed out:
Once upon a time there was

The testcase is flawed because the input has the word a twice so the program should break out of the loop here Once upon a time there was.
