Homework Helper

Part 1: Create Personal Info (dict)

Create a dictionary called personal_info that includes the following keys. Assign values to the keys: full_name, years, location, and favorite_food. The full_name should be a string, years an integer, location a string, and favorite_food a string.

See Answer

```python personal_info = { "full_name": "John Doe", "years": 25, "location": "New York", "favorite_food": "Pizza" } ```

Part 2: Create a List of Activities (list)

Create a list called activities that includes three of your favorite activities as strings. Print the activities list.

See Answer

```python activities = ["Running", "Reading", "Gaming"] print(activities) ```

Part 3: Add Activities to Personal Info (dict and list)

Add the activities list to the personal_info dictionary under the key activities. Print the updated personal_info dictionary.

See Answer

```python personal_info["activities"] = activities print(personal_info) ```

Part 4: Check Availability of an Activity (bool)

Choose one of your activities and create a boolean variable called activity_available. Set activity_available to True if your activity is available today, otherwise set it to False. Print a message using activity_available like: “Is «your activity» available today? «True/False»”

See Answer

```python activity_available = True # or False print(f"Is Running available today? {activity_available}") ```

Part 5: Total Number of Activities (int)

Create a variable called total_activities and set it to the number of activities in your activities list. Print a message like: “I have «total_activities» activities.”

See Answer

```python total_activities = len(activities) print(f"I have {total_activities} activities.") ```

Part 6: Favorite Activities (tuple)

Create a tuple called favorite_activities that contains your two most favorite activities. Print the favorite_activities tuple.

See Answer

```python favorite_activities = ("Running", "Reading") print(favorite_activities) ```

Part 8: Consider a New Skill (NoneType)

You are thinking about learning a new skill. Create a variable called new_skill and set it to None (you haven’t decided yet). Print the value of new_skill.

See Answer

```python new_skill = None print(new_skill) ```

Part 9: Calculate Total Hobby and Skill Cost (float)

Assume each activity costs $5 to pursue and each skill costs $10 to develop. Create a variable called total_cost as a float, and calculate how much it would cost to develop all your activities and skills. Print the total cost.

See Answer

```python total_cost = (len(activities) * 5) + (len(skills) * 10) print(f"Total cost: ${total_cost}") ```
