I have been working on this addition to the RPS game. I have installed prompt-toolkit 3.0.5. As I have been coding along with you, I have received the following error:
File "/PycharmProjects/RPS/RPS-v8.py", line 157
word_comp: object = word_completer(roll_names)
^
SyntaxError: invalid syntax

I can't figure out what is causing the error as I have attempted to follow your code...there were some differences that came up when I entered the WordCompleter...the autofill had me use word_completer for example. Below is the section of code that relates:

def get_roll(player_name, roll_names):
print(f"Available rolls: {', '.join(roll_names)}"
# for index, r in enumerate(roll_names, start=1):
# print(f"{index}. {r}")

word_comp = word_completer(roll_names)
roll = prompt(f"{player_name}, what is your roll: ", completer=word_comp)

text = input(f"{player_name}, what is your roll?")
selected_index = int(text) - 1

if not roll or roll not in roll_names:
    print(f"Sorry {player_name}, {roll} is not valid!")
    return None

return roll

Hi! I also had some problems with this lesson recently. It's much more advanced than the stuff before and I'm not sure about some stuff there. Definitely not something that I could replicate myself. Perhaps studing documentary will help me, but I'm not used to it.
I think that I can help you though. WordCompleter is function imported from Prompt Toolkit library and it's need to be written excatly to the letter, with capital letters and without spaces. It seems that you wrote "word_completer" instead. Try using "WordCompleter" and see if it works. It fifth line of the code you posted, just after comments with excluded code.

Ah, it looks like you already know that! Sorry for misunderstaing. Perhaps you should ignore the correction and force WordCompleter there? I don't have this problem, PyCharm completes it correctly for me, and I have the same version of library.

I went in and made the changes to use WordCompleter. I'm still throwing an error:

File "/PycharmProjects/RPS/RPS-v8.py", line 157
word_comp = WordCompleter(roll_names)
^
SyntaxError: invalid syntax

The code that is involved is below:

def get_roll(player_name, roll_names):
print(f"Available rolls: {', '.join(roll_names)}."
# for index, r in enumerate(roll_names, start=1):
# print(f"{index}. {r}")

word_comp = WordCompleter(roll_names)
roll = prompt(f"{player_name}, what is your roll: ", completer=word_comp)

text = input(f"{player_name}, what is your roll?")
selected_index = int(text) - 1

if not roll or roll not in roll_names:
    print(f"Sorry {player_name}, {roll} is not valid!")
    return None

return roll

Are you sure you have the library imported? Looks like it doesn't know that WordCompleter is a function and only functions can have parenthesis.
Remember to try the code in Python Shell and not in PyCharm. For that you also need to open the file in virtual environment with the library installed. Perhaps you're somewhat executing the file in another environment where there is no prompt-toolkit? Try running the code in PyCharm terminal, you should get some other error if this is the case (because you apparently installed the library using PyCharm but it can't show prompts).

[GeekDGirl]

Yes, I have the library imported. At this point, I'm still running the program in PyCharm because it's throwing the error on the variable word_comp.

[grze744]

It will not work in PyCharm. Try the code in shell, perhaps there is no problem here.

Hi folks. You can't use the fancy terminal tools like prompt-toolkit within PyCharm because it's not a real terminal. Just copy the run command you see pycharm using when you press go and past it into a ternimal / command prompt.
