No need for the space after "room".

"while hp:" would be idiomatic, but you probably want "while hp > 0"

You meant "random_number", I'm sure ;).

Don't comment lines unless the comment says more than the line.

You don't need the brackets. Try to avoid redundant brackets where
they don't clarify anything.
Additionally, you should probably be more lenient and consistent with
answers. Maybe something like:
if des.casefold() in ("y", "yes"):
and its counterpart
if des.casefold() in ("n", "no"):

You should avoid spaces between the function and the brackets.

Think carefully here -- do you want to have a round when monster_hp is
greater *or equal* to 0? Maybe you would rather only if it's alive (hp
> 0)?

Gah! You just kill him off? Are you sure you don't want to use a
"break" or "return" to quit the loop or function?

As a whole, +1 for the good naming, decent attempt at spacing and a
mostly-sane layout.
> this is the code i'm making. as the subject says im new to while statements. i am having problems with the monster battle part, it takes health away from the "monster" but as soon as it gets to 0 or less i'd like the code to start from the top and ask you to roll the die again. any help on this would be greatly appreciative
PS: I'd use a state machine for times like this, eg.
import random
def prompt(action, retort_invalid=None):
while "asking for reponse":
response = input("Would you like to {}?".format(action)).casefold()
if response in ["y", "yes"]:
return True
elif response in ["n", "no"]:
return False
else:
if retort_invalid is not None:
print(retort_invalid)
def room():
state = "wandering"
while "adventuring":
if state == "idle":
if prompt("wander around")
print("Rolling the die...")
roll = random.randint(1, 2)
print("You rolled a {}.".format(roll))
if roll == 1:
monster_hp = 10
print("Oh no! A Monster!")
state = "facing monster"
else:
print("You find nothing")
else:
print("Maybe next time!")
return
elif state == "facing monster":
will_attack =
if prompt("attack", "You and the monster just stare at
one another"):
state = "attacking"
else:
print("you run away")
state = "idle"
elif state == "attacking":
damage_done = random.randint(0, 5)
monster_hp -= damage_done
print("You attack to do", damage_done, "damage")
print("The monster takes a hit, it has", monster_hp, "hp left")
if monster_hp <= 0:
state = "idle"
room()
The advantage of this is everything sits at the same level so you know
whether you've covered all options and permutations of options. It's
only longer because I made the "prompt" function which is more
rigorous than the current method.
