Q8A & Q8B: Using the castaway_details data, what is the percentage of total extroverts and introverts that have played the game (count players only once even if they have played in more than one season). Do not count contestants without a personality type listed in your calculations. Save these percentages as Q8A and Q8B respectively. Note: Round all percentages to two decimal points and write as a float (example: 55.57).

To calculate the percentage of total extroverts that have played the game, we need to divide the number of extroverts by the total number of players (excluding contestants without a personality type listed), and then multiply the result by 100.

First, let's count the number of extroverts:
```python
extroverts = castaway_details[castaway_details['Personality Type'] == 'Extrovert']
total_extroverts = len(extroverts)
```

Next, let's count the total number of players by excluding contestants without a personality type listed:
```python
players = castaway_details.dropna(subset=['Personality Type'])
total_players = len(players)
```

Finally, we can calculate the percentage of extroverts as Q8A:
```python
Q8A = (total_extroverts / total_players) * 100
```

For the percentage of introverts, we can follow the same steps. Let's count the number of introverts first:
```python
introverts = castaway_details[castaway_details['Personality Type'] == 'Introvert']
total_introverts = len(introverts)
```

And then calculate the percentage of introverts as Q8B:
```python
Q8B = (total_introverts / total_players) * 100
```

Round the percentages to two decimal points and save them as floats:
```python
Q8A = round(Q8A, 2)
Q8B = round(Q8B, 2)
```

The final values of Q8A and Q8B are the percentages of total extroverts and introverts that have played the game, respectively.

To calculate the percentage of total extroverts and introverts that have played the game, we need to consider the "personality_type" column in the "castaway_details" data.

First, we need to identify the total number of unique players in the dataset. We will count each player only once, even if they have played in more than one season.

Then, we will calculate the number and percentage of extroverts and introverts:

Q8A: Percentage of Total Extroverts
Q8B: Percentage of Total Introverts

Here are the step-by-step instructions to calculate these percentages:

1. Count the total number of unique players in the dataset (counting each player only once, even if they have played in multiple seasons). Save this count as "total_players".

2. Filter the dataset to include only the players with a personality type listed (excluding contestants without a personality type). Save this filtered dataset as "players_with_personality_type".

3. Count the number of extrovert players in the "players_with_personality_type" dataset. Save this count as "extrovert_players".

4. Count the number of introvert players in the "players_with_personality_type" dataset. Save this count as "introvert_players".

5. Calculate the percentage of extrovert players using the formula: (extrovert_players / total_players) * 100. Round the result to two decimal points.

6. Calculate the percentage of introvert players using the formula: (introvert_players / total_players) * 100. Round the result to two decimal points.

7. Save the calculated percentages as Q8A and Q8B respectively, following the format specified (e.g., 55.57).

Please note that without access to the actual data, I am unable to provide you with the specific counts and percentages. You will need to use the given instructions and perform the calculations on the actual dataset to obtain the required results.
