python 计算斜率

  

   

    

     

    
    

     

       p1 = [1, 2]
     
    
   

    

     

    
    

     

       p2 = [3, 4]
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

       xielv = abs((p1[1] - p2[1]) / (p1[0] - p2[0] + 1e-5))
     
    
   

    

     

    
    

     
 if xielv > 0.25 and xielv < 2:
     
    
   

    

     

    
    

     

       print(xielv)
     
    
  
 

根据斜率求角度：

  

   

    

     

    
    

     

      import math
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

      if __name__ == '__main__':
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

       p1 = [1, 2]
     
    
   

    

     

    
    

     

       p2 = [3, 4]
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

       xielv = abs((p1[1] - p2[1]) / (p1[0] - p2[0] + 1e-5))
     
    
   

    

     

    
    

     
 if xielv > 0.25 and xielv < 2:
     
    
   

    

     

    
    

     

       print(xielv)
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

       print(math.atan(xielv))
     
    
   

    

     

    
    

     

       print(math.degrees(math.atan(xielv)))
