I am a beginner to Python, and my professor does poor job explaining the differences between loops. I wanted to ask this community the differences between For loops and While loops. I looked at various resources but what I am confused about is how for loops have no counter to bring them back to the beginning like while loops:
I have the following code written in for() loop but my goal is to change it to a while loop. The code is not what is important is how to change this code to a While() loop. 

```
for r_ow in range(Height_box):
    for c_col in range(Width_box):
        gridpoint = box * row + column
        if gridpoint in gridList:
            box[r_ow][c_col] = "Inside Box"
        else:
            outsideBox = (CurrentBox(boxWidth,Boxedge))
            ctr = 0
            for Box_edges in Box:
                if eval(Box(boxWidth,boxHeight,box_edges,box_point)):
                    if box_edge in gridList:
                        ctr += 1
            Bow[r_ow][c_col] = str(int(box[r_ow][c_col]) + ctr)

```

So far, I have gotten to a point where I think this is what it suppose to look like but now i get stuck in a CMD infinite loop.

```
row = 0
while r_ow < boxHeight:
    column = 0
    while c_col < boxWidth:
        gridpoint = box * row + column
        if gridpoint in gridList:
            box[r_ow][c_ol] = "Inside Box"
        else:
            outsideBox = (CurrentBox(boxWidth,Boxedge))
            ctr = 0
            while ctr < Boxes: 
                if eval(Box(boxWidth,boxHeight,box_edges,box_point)):
                    if box_edge in gridList:
                    ctr += 1
        Bow[r_ow][c_col] = str(int(box[r_ow][c_col]) + ctr)
    column += 1
row += 1
return box  

```

Can anyone give some advice as to how to format the first code into while loops()?

thank you very much!!
