This works outside of workspaces. The "Bummer! Try again!" message is lacking in helpfulness. Would appreciate a hand.

when I run this in Atom with python 3.6.2 it works fine. Only thing I can think of is it's not returning a tuple?

movement.py
# EXAMPLES:
# move((1, 1, 10), (-1, 0)) => (0, 1, 10)
# move((0, 1, 10), (-1, 0)) => (0, 1, 5)
# move((0, 9, 5), (0, 1)) => (0, 9, 0)

def move(player, direction):
    x, y, hp = player
        if direction == (-1, 0):
        x -= 1
        if x < 0:
            x = 0
            hp -= 5
    if direction == (1, 0):
        x += 1
        if x > 9:
            x = 9
            hp -= 5
    if direction == (0, -1):
        y -= 1
        if y < 0:
            y = 0
            hp -= 5
    if direction == (0, 1):
        y += 1
        if y > 9:
            y = 9
            hp -= 5  
    return x, y, hp
move((0, 9, 5), (0, 1))

What I did here was I unpacked direction as a tuple as well

a , b = direction

Since what we're doing here is merging the two arguments to return the result, I then said

x = x + a
y = y + b

Then, you can simply say if x > 9: x = 9, etc.

Thanks Jimmy - I'll give that a try.
