'int' Object Is Not Callable Only Appears Randomly

Sometimes this code works just fine and runs through, but other times it throws the int object not callable error. I am not real sure as to why it is doing so. for ship in ships:

Solution 1:

You are trying to call (use the ..(...) syntax) on an integer here:

ship.location[size][1]((ship.location[0][0], \
                        ship.location[0][1] - size))

ship.location[size][1] is an integer, and you are trying to call it by passing in the tuple (ship.location[0][0], ship.location[0][1] - size) as the arguments.

Your code makes this mistake in more than one place; other examples include

ship.location[size][1]((ship.location[0][0], \
                    ship.location[0][1] + size))

and

ship.location[size][1] \
    ((ship.location[0][0] - size, \
      ship.location[0][1]))

and

ship.location[size][1] \
    ((ship.location[0][0] + size, \
      ship.location[0][1]))

The backslash there still joins the physical line into a logical line, so the (...) calls still apply to the integers.

It is not clear to me what you wanted to do with that expression, however, so I can't offer any remedy here.

Solution 2:

In any spot where the code looks like this:

ship.location[size][1]((ship.location[0][0], \
              ship.location[0][1] - size))

The simple solution was that I needed to assign it to the location:

ship.location[size] = ((ship.location[0][0],ship.location[0][1] - size))
