TicTacToe game | Starting with python after learning JS

I've been coding since about one year in JS now, and started with Python this week. I've created this TicTacToe game to get familiar with Python and would like to know what you think about this code, if it seems unusual in some way, or you'd have done something different, etc.

```
class TicTacToe(object):

# Init
def __init__(self, rows, columns, nInARow):
# Create Field
self.field = [[None for y in range(rows)] for x in range(columns)]

#Set Variables
self.currentPlayer = "X"
self.nInARow = nInARow
self.playing = True

print ("A %sx%s TicTacToe game has been created\nYou need %s in a row to win!\nGood luck, have Fun!\n\n" % (rows, columns, nInARow))

#Updates the game
def update(self):
print("Player %s's turn" % (self.currentPlayer))

self.renderField()
self.getInput()
if self.checkWin():
print ("\nPlayer %s won the game!" % (self.currentPlayer))
self.renderField()
self.playing = False

#Update current Player
self.currentPlayer = "X" if self.currentPlayer == "O" else "O"

#Returns True if game is finished
def gameEnded(self):
return (not self.playing)

#Renders the field to the console
def renderField(self):

#Loop through the field
for y in range (len(self.field)):
line = ""
for x in range (len(self.field[y])):
#Add Value of field or "_" (or "" if last row)
line += self.field[y][x] if self.field[y][x] else ("_" if y len(self.field[0]) - 1) or
(yCoord len(self.field) - 1) or
(self.field[yCoord][xCoord] != None)):
xCoord = int(input("Please enter the x-coordinate (1 to %s): " % (len(self.field[0])))) - 1
yCoord = int(input("Please enter the y-coordinate (1 to %s): " % (len(self.field)))) -1
print()

#Set box
self.field[yCoord][xCoor

Style

First, a style check. Python has an official style-guide, PEP8, which programmers are encouraged to adhere to. It recommends using lower_case for variables and functions (and PascalCase for classes, which you did use).

In addition, Python has docstrings, defined in PEP257, which allow adding a string describing a class or function. These are usually of the form

def f(a, b):
    """Add `a` and `b`"""
    return a + b

or, if you need multiple lines:

def g(*args):
    """
    Sum all `args`

    Randomly does something else.
    """
    if random.random() > 0.1:
        return sum(args)
    raise RuntimeError("Bad luck")

In Python we try to have as few unnecessary things as possible. One of these things are redundant parenthesis. The if keyword (and similar the while and for keywords) don't need parenthesis around their arguments (and neither did the print keyword in Python 2.x, but since it is a function in Python 3.x you can add them for compatibility).

You should always guard the execution of your code with a if __name__ == '__main__': guard. This allows you to simply import all your functions from another script without actually starting the game.
