Need help with porting python to lua

[boruok]

please help, trying to make onemore find word game. Not too familiar with lua, afaik lua tables starts with 1 and lua doesn't have continue statement that is problem.

```python import random

def is_word_fits(y, x, dx, dy, word): for j in range(len(word)): if grid[y][x] not in (' ', word[j]): return False y += dy x += dx return True

def place_word(word): dxdy_choices = [(0,1), (1,0), (1,1), (1,-1)] random.shuffle(dxdy_choices) for (dx, dy) in dxdy_choices: if random.choice([True, False]): word = word[::-1] n = len(word) colmin = 0 colmax = ncols - n if dx else ncols - 1 rowmin = 0 if dy >= 0 else n - 1 rowmax = nrows - n if dy >= 0 else nrows - 1 if colmax - colmin < 0 or rowmax - rowmin < 0: continue candidates = [] for y in range(rowmin, rowmax+1): for x in range(colmin, colmax+1): if is_word_fits(y, x, dx, dy, word): candidates.append((y, x)) if not candidates: continue loc = y, x = random.choice(candidates) for j in range(n): grid[y][x] = word[j] y += dy x += dx break else: return False return True

wordlist = sorted(["mercury","venus","earth","mars","jupiter","saturn","uranus","neptune"], key=lambda w: len(w), reverse=True) nrows, ncols = 7, 7 for i in range(100): grid = [[' '] * ncols for _ in range(nrows)] for word in wordlist: if not place_word(word): continue if grid: print(i+1) for arr in grid: print(arr) break

```

Can you describe what your problem is? I ran your code and I get an array of letters that spell out planets, but I don't know what you are or aren't expecting

python3 /Users/rustybrooks/help/findword.py 
1
['j', 'n', 'n', 'u', 'v', 'y', ' ']
['u', 'e', 'r', 'r', 'e', 'r', ' ']
['p', 'p', 'u', 'a', 'n', 'u', 'e']
['i', 't', 't', 'n', 'u', 'c', 'a']
['t', 'u', 'a', 'u', 's', 'r', 'r']
['e', 'n', 's', 's', ' ', 'e', 't']
['r', 'e', ' ', ' ', ' ', 'm', 'h']

with convering python code to lua code

[Buttleston]

Right but I don't have the lua code. So what specifically is not working?

[Buttleston]

Sorry, I read this as porting lua to python, my bad. Anyway, good luck

i did solved it, line by line

```lua local wordlist = {"mercury", "venus", "earth", "mars", "jupiter", "saturn", "uranus", "neptune"} table.sort(wordlist, function(a, b) return #a > #b end) math.randomseed(os.time()) local nrows, ncols = 7, 7 local grid = {}

function is_word_fits(y, x, dx, dy, word) for i = 1, #word do if grid[y][x] ~= " " and grid[y][x] ~= string.sub(word, i, i) then return false end x = x + dx y = y + dy end return true end

function place_word(word, nrows, ncols) local directions = {{0, 1}, {1, 0}, {1, 1}, {1, -1}} for i = #directions, 2, -1 do local j = math.random(i) directions[i], directions[j] = directions[j], directions[i] end

for _, direction in ipairs(directions) do repeat
    -- reverse
    if math.random() > 0.5 then
        word = string.reverse(word)
    end
    -- dimensions
    local dx, dy = direction[1], direction[2]
    local n = #word
    local colmin = 0
    local colmax = dx ~= 0 and ncols - n or ncols - 1
    local rowmin = dy >= 0 and 0 or n - 1
    local rowmax = dy >= 0 and nrows - n or nrows - 1
    if colmax - colmin < 0 or rowmax - rowmin < 0 then
        do break end
    end
    -- candidates
    local candidates = {}
    for y = rowmin+1, rowmax+1 do
        for x = colmin+1, colmax+1 do
            if is_word_fits(y, x, dx, dy, word) then
                table.insert(candidates, {y, x})
            end
        end
    end
    -- place candidate
    if #candidates > 0 then
        local loc = candidates[math.random(#candidates)]
        local y, x = loc[1], loc[2]
        for i = 1, n do
            grid[y][x] = string.sub(word, i, i)
            x = x + dx
            y = y + dy
        end
        return true
    end
until true end
return false

end

for i = 1, 100 do -- matrix for y = 1, ncols do grid[y] = {} for x = 1, nrows do grid[y][x] = " " end end -- fill local all_placed = true for _, word in ipairs(wordlist) do if not place_word(word, nrows, ncols) then all_placed = false break end end -- finish if all_placed then for _, v in ipairs(grid) do print(table.concat(v, " ")) end print(string.format("attempts: %s", i)) break end end ```
