I need help on Long -Range Division

Can someone please have a look at my codes of Long-Range Division -see below snip.
No sure why the hero is killed at the end.

Below are my codes

Destroy the mines!

Use say to call out the range to the mines.

Use division to calculate the range.

enemy = hero.findNearestEnemy()
distanceToEnemy = hero.distanceTo(enemy)

Say first Range: distanceToEnemy divided by 3

hero.say(“first Range”+ distanceToEnemy/3)
hero.say (“Fire!”)

Say second range: distanceToEnemy divided by 1.5

hero.say(“second Range”+ distanceToEnemy/1.5)
hero.say (“Fire!”)
hero.say(“Woo hoo!”)
hero.say(“Here we go”)
while True:

You didn’t define the enemy variable, so this results an error, do this instead:

while True:
    enemy = hero.findNearestEnemy()  # Define the enemy!
    if enemy:  # Check for the existance of the enemy

Please format your code, and, as @Watamelon said, you have to define enemy before using it
