Description

In this stage, you will implement the new game function and the game stats.

You need to store important variables when creating a new game such as:

• The username. You will need it in a later stage for the save file path.
• The character attributes: Name, Species, and the Gender.
• The inventory: Snack, Weapon, and Tool.
• The difficulty level: 1. Easy, 2. Medium and 3. Hard. The user should be able to select the difficulty level either by the word or the index. Difficulty selection should be case-insensitive.
• The remaining lives: 5 for an easy difficulty level, 3 for a medium one, and 1 for a hard one. You don't need to take the number of lives as input, it should be calculated on the basis of the level that the user chooses.

You might want to divide variables into sections to make the output more pleasing to the player, that won't be tested.

Output highlighted substrings from a list before corresponding input, so that player can determine what data he/she is entering. You should get the game variables in the same order as in the Examples section.

When all the variables have been entered your program should output the game stats. You can use the following formatting:

Good luck on your journey, {username}!
Your character: {name}, {species}, {gender}
Your inventory: {snack}, {weapon}, {tool}
Difficulty: {difficulty}
Number of lives: {lives}

Note, that difficulty level should be printed as a word (Easy, Medium or Hard)

Also, a player can make a mistake by choosing to create a new game, so give them an option to go back to the main menu: Enter a username ('/b' to go back):.

Don't forget to handle incorrect input of difficulty the same way as before with option selection!

Objectives

In this stage, your program should:

1. Create and store the game state with variables such as the inventory, character attributes, difficulty, remaining lives, and the username.
2. Have the option to go back to the menu with /b command before creating a new game.
3. Before the new game starts, output the message Good luck on your journey, {username}! with the game stats below such as the character traits, inventory, difficulty, and the number of lives.
4. Handle incorrect input of difficulty.

Examples

The greater-than symbol followed by a space (> ) represents the user input. Note that it's not part of the input.
