I wrote a simple code on python, but it doesn't work as intended can someone help me

Question

This code will display an image where the 0 is going to be ' ', and the 1 is going to be '*'. This will reveal an image:

   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 ]
        ]

The image to be revealed should be:

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

The code that I need someone to help me with:

   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

What my code produces:

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

Answer 1

Don't be scare to use nested for loops.

for row in picture:
    
    line = ""
    for i in row:
        if i == 0:
            line += " "
        else:
            line += "*"
    print(line)

Answer 2

Simpler method:

for row in picture:
    for col in row:
        print(end=' *'[col])
    print()

Very short version:

'\n'.join(''.join(map(' *'.__getitem__, row)) for row in picture)
