3.11. Health Bar

You are a warrior who is given a difficult quest to complete. In this journey, you encounter various types of troubles including monsters. You have to fight them off to continue and you want to see how much the next attack will hurt you.

Write a function called health_bar to show your current health status. This function takes 3 integers: (1) your base health, (2) your current health and (3) the damage you take. The function returns your current health status as a string with “X”s (remaining health) and “_”s (missing health). Here are some accompanying specifications:

• Your base health and the damage you take will always be a positive integer.

• The damage you take can be more than your current health.

• The length of your health bar string must match your base health.

Consider the following case: If your base health is 9 and your current health is 7 when you take 3 damage, your current health bar becomes “XXXX_____”.

Hint: You can use string repetition.

Sample I/O:

>>> health_bar(11, 11, 4)
'XXXXXXX____'

>>> health_bar(8, 2, 6)
'________'

def health_bar(base_health, current_health, damage):
    remaining_health = current_health - damage

    if(remaining_health < 0):       #deciding if you are dead or not
        remaining_health = 0

    missing_health = base_health - remaining_health
    health_bar = "X"*remaining_health + "_"*missing_health

    return health_bar
