help with type hints

[resserone13v2.0]

When I use type hints like this

def average_streak_len(streak_history: dict [str, str]):
    # Create a dictionary to store the most common value for each team
    average_streaks = {}

    # Iterate through each key-value pair in the input dictionary
    for team, value_list in streak_history.items():
        # Count the occurrences of each value in the value_list
        value_count = {}
        for value in value_list:
            value_count[value] = value_count.get(value, 0) + 1

        # Find the value with the maximum count for this team
        max_value = max(value_count, key=value_count.get)

        # Store the most common value for this team
        average_streaks[team] = max_value

    return average_streaks

I get an error that says

TypeError: 'type' object is not subscriptable

why is this?

@resserone13v2-0 Do you use the last version of Pythonista because the syntax you use needs Python >= 3.9

See here

[resserone13v2.0]

@cvp OK. I will give this a read through and check which version of python I'm running.. thanks

[resserone13v2.0]

@cvp I think I'm running 3.11.
I typed python -v in the cmd line
printed this
\PythonSoftwareFoundation.Python.3.11_3.11.1008.0_

I think you are not in Pythonista. There is no command line and this command is not accepted in console line.
Are you on a PC or a MAC ?

And if I try your script, I don't get an error in Pythonista 3.4 which runs Python 3.10

@cvp pc my IDE is spyder. Maybe its the version that spyder is running. No worries. Not a big deal. Ive just been working on making my code more clean. Im sure ill figure it out and the code is doing what i need it to. There is a lot to learn. Not just a language but installing packages running different versions of a language. Storing files. For me its good cuz there is always something new to learn

@resserone13v2-0 understood but this is a Pythonista forum....

[resserone13v2.0]

@cvp ok. Ill keep make sure all my post are pythonista related.

@resserone13v2-0 you can always search stack overflow for your error

There are a few workarounds depending on the version you are using.
