How can I make this if statement loop

Question

I am making a top-down shooter also I am new to coding so I will make mistakes but how do I loop this if statement because every time I shoot I loose 1 ammo and I have 6 bullets
and if I use all 6 the if statement gets triggered but it only triggers once then doesn't work anymore. Sorry I am bad at typing

if Input.isactionpressed("uifire") and canfire:
var bulletinstance = bullet.instance()
bulletinstance.position = $BulletPoint.getglobalposition()
bulletinstance.rotationdegrees = rotationdegrees
bulletinstance.applyimpulse(Vector2(), Vector2(bulletspeed, 0).rotated(rotation))
gettree().getroot().addchild(bulletinstance)
ammo -= 1
print("Taking 1% ammo")
canfire = false
yield(gettree().createtimer(firerate), "timeout")
can_fire = true
**if ammo == 0: ***#This entire if code is my problem***
**print("Notice 0% ammo")
reload = true
can_fire = false
yield(get_tree().create_timer(reload_speed), "timeout")
print("Finished Reload")
can_fire = true****

Answer 1

The ammo is never set back to 6 (ammo = 6). This should happen next to (or instead of) the line reload = true (not sure whether this line has a purpose anywhere else, but in this part of the code the reload value is never used for anything).

I was super tired when I made that code and pretty much after I sent this question I did the ammo = 6 But this did work and Thank You
