body: <p>I am a beginner</p>
  <pre><code>import pygame as py
  from math import sqrt, pow
  
  nuclear = py.transform.scale(py.image.load('nuclear.png'),(300, 300))
  def collosion(enemyX,enemyY,fireX,fireY):
      distance = sqrt(pow(enemyX - fireX, 2) + pow(fireY - enemyY, 2))
      if distance &lt;= 100:
          return True
      else:
          return False
  
  collosion1 = collosion(enemy1_x,enemy2_y,shoot1X + 50, shoot1Y + 60)
      if collosion1:
          window.blit(nuclear,(enemy1_x,enemy2_y))
          enemy1_x = 1400
          enemy2_y = 530
          shoot1X = tankX
          shoot1Y = tankY
          shoot_now = 'not fired'
          shoot1 = py.transform.scale(py.image.load('shoot1.png'), (70, 30))
