Hello , i completed the movement challenge as below but the code looks very childish to me and i want to improve it , any suggestion ???
x, y, hp = player
a,b = direction
if a < 0:
x= x-abs(a)
else:
x = x+a
if b < 0:
y= y-abs(b)
else:
y = y+b
if x < 0:
x = 0
hp = hp-5
elif y < 0:
y = 0
hp = hp-5
elif x > 9:
x = 9
hp = hp-5
elif y > 9:
y = 9
hp = hp-5
return x,y,hp
[MOD: added ```python formatting -cf]

# this
if a < 0:
x= x-abs(a)
else:
x = x+a
if b < 0:
y= y-abs(b)
else:
y = y+b
# is equivalent to
x += a
y += b
The rest is python's version of a case statement:
# case statement.
if x < 0:
x = 0
hp = hp-5
elif y < 0:
y = 0
hp = hp-5
elif x > 9:
x = 9
hp = hp-5
elif y > 9:
y = 9
hp = hp-5
# final return
return x,y,hp
The only other suggestion would be to improve on styling (see PEP8). Spaces after commas and around operators in assignments improve readability.
