Yes you are :)
"for j in range(10):..." means:
1. Build a list [0,1,2,3,4,5,6,7,8,9]
2. For element in this list (0, then 1, then 2,...), set j to that
value then execute the code inside the loop body
To simulate "for(<initialisation>; <condition>; <increment>) <body>"
you have to use while in Python:
<initialisation>
while <condition>:
<body>
<increment>
Of course in most case it would not be the "pythonic" way of doing
it :)
