我在python上写了一个简单的代码,但它没有达到预期的效果。有人能帮我吗

此代码将显示一个图像,其中0将是“”,1将是“*”。这将显示一个图像:

   picture = [
       [0,0,0,1,0,0,0 ],
       [0,0,1,1,1,0,0 ],
       [0,1,1,1,1,1,0 ],
       [1,1,1,1,1,1,1 ],
       [0,0,0,1,0,0,0 ],
       [0,0,0,1,0,0,0 ]
        ]

要展示的图像应该是:

   *   
  ***  
 ***** 
*******
   *   
   *

我需要有人帮助我的代码:

   picture = [
       [0,0,0,1,0,0,0 ],
       [0,0,1,1,1,0,0 ],
       [0,1,1,1,1,1,0 ],
       [1,1,1,1,1,1,1 ],
       [0,0,0,1,0,0,0 ],
       [0,0,0,1,0,0,0 ]
        ]
 row=0
 col=0
 picture[row][col]

 while row<=5:

 while col<=6:
  if picture[row][col]== False:
    picture[row][col]=" "
    col=1+col
  else:
    picture[row][col]="*"
    col=col+1

  print(

    str(picture[row][0]) +" "+ str(picture[row][1]) +" "+ 

  str(picture[row][2])+" "+str(picture[row][3])+" "+str(picture[row][4])

    +" "+str(picture[row][5])+" "+str(picture[row][6])
          )

 row=row+1

我的代码产生了什么:

  0 0 1 0 0 0
    0 1 0 0 0
      1 0 0 0
      * 0 0 0
      *   0 0
      *     0
      *
