Some of the problems   for i in range 6               for j in range 6     should be   range 6

This error could be an indication that variable with the same name has been used in your code earlier  but for other purposes  Possibly  a variable has been given a name that coincides with the existing function used later in the code

The error    int  object has no attribute    getitem      means that you re attempting to apply the index operator    on an int  not a list  So is col not a list  even when it should be  Let s start from that   Look here   col     0 for col in range 5   for row in range 6     Use a different variable name inside  looks like the list comprehension overwrites the col variable during iteration   Not during the iteration when you set col  but during the following ones

you can also covert int to str first and assign index to it then again convert it to int like this   int str x  n     where x is an integer value
