    <p>I'm writing a class for a simple game of 4 in a row, but I'm running into a problem calling a method in the same class. Here's the whole class for the sake of completeness:</p> <pre><code>class Grid: grid = None # creates a new empty 10 x 10 grid def reset(): Grid.grid = [[0] * 10 for i in range(10)] # places an X or O def place(player,x,y): Grid.grid[x][y] = player # returns the element in the grid def getAt(x,y): return Grid.grid[x][y] # checks for wins in a certain direction def checkLine(player,v,count,x,y): x = x+v[0] y = y+v[1] if x &lt; 0 or x &gt; 9: return if y &lt; 0 or y &gt; 9: return if Grid.grid[x][y] == p: count = count+1 if count == 4: return True checkLine(player,v,count,x,y) return False # returns the number of the player that won def check(): i = 'i' for x in range(0,10): for y in range(0,10): if Grid.grid[x][y] &gt; 0: p = Grid.grid[x][y] f = checkLine(p,0,array(i,[1,0]),x,y) if f: return p f = checkLine(p,0,array(i,[0,1]),x,y) if f: return p f = checkLine(p,0,array(i,[1,1]),x,y) if f: return p f = checkLine(p,0,array(i,[-1,0]),x,y) if f: return p f = checkLine(p,0,array(i,[0,-1]),x,y) if f: return p f = checkLine(p,0,array(i,[-1,-1]),x,y) if f: return p f = checkLine(p,0,array(i,[1,-1]),x,y) if f: return p f = checkLine(p,0,array(i,[-1,1]),x,y) if f: return p return 0 reset = staticmethod(reset) place = staticmethod(place) getAt = staticmethod(getAt) check = staticmethod(check) checkLine = staticmethod(checkLine) </code></pre> <p>I'm trying to call checkLine() from check(), but I get the error "<strong>NameError: global name 'checkLine' is not defined</strong>". When I call Grid.checkLine() instead, I get "<strong>TypeError: 'module' object is not callable</strong>"</p> <p>How do I call checkLine()?</p> <p>EDIT:</p> <p>@beer_monk</p> <pre><code>class Grid(object): grid = None # creates a new empty 10 x 10 grid def reset(self): Grid.grid = [[0] * 10 for i in range(10)] # places an X or O def place(self,player,x,y): Grid.grid[x][y] = player # returns the element in the grid def getAt(self,x,y): return Grid.grid[x][y] # checks for wins in a certain direction def checkLine(self,player,v,count,x,y): x = x+v[0] y = y+v[1] if x &lt; 0 or x &gt; 9: return if y &lt; 0 or y &gt; 9: return if Grid.grid[x][y] == p: count = count+1 if count == 4: return True checkLine(self,player,v,count,x,y) return False # returns the number of the player that won def check(self): i = 'i' for x in range(0,10): for y in range(0,10): if Grid.grid[x][y] &gt; 0: p = Grid.grid[x][y] for vx in range(-1,2): for vy in range(-1,2): f = self.checkLine(p,0,array(i,[vx,vy]),x,y) if f: return p return 0 reset = staticmethod(reset) place = staticmethod(place) getAt = staticmethod(getAt) check = staticmethod(check) checkLine = staticmethod(checkLine) </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
