(a)

def main():
      maze= open('maze.txt','r+')
      for line in maze:
          line = line.strip()
          print line
       maze.close()
print
start(maze,x,y)
print maze[y][x]

(b)

def start(maze,x,y):
         for x in range(0,len(maze)):
                 if maze[y][x] == "s"
                 print maze[y][x]
                 return x, y

question (b): write a function that walks through the maze and attempts to find exit. As a minimum, the function should accept two argument that specify the starting row and column number.

print maze[y][x]

This code won't run. You don't call main() and neither maze, x, or y are defined before calling the start(maze, x, y) function. "How To Think Like A Computer Scientist" is a good learning tool; "Functions" Chapter (3.5) = http://www.greenteapress.com/thinkpython/html/book004.html

How can I move to row 4 and replace it with x, and move forward to col 2 of row 4.

Member Avatar for adam321

x= "x"
Squares= 399
def start():
for i in range(squares):
Maze.append(x)
return Maze
print"\n\t", Maze[60], ",", Maze[61], ",", Maze[62]

print(start())

I am getting invalid sytamic for "\n\t"
