Question

Hi everyone. This is what I did for problem 3 homework 6 for 2011spring it says there's indentatiion problem but I am getting confused. Is there anyone who knows where the problem lies?

Thanks a lot~


def runSimulation(num_robots, speed, width, height, min_coverage, num_trials,
robot_type):
time=0
for trial in range(num_trial):
room=RectangularRoom(width,height)
robot=[]
for ii in range(num_robots):
robot.append(robot_type(room,speed))
while room.getNumCleanedTiles()/room.getNumTiles() < min_coverage:
for ii in range(num_robots):
robot[ii].updatePositionAndClean()
time=time+1
return time/num_trial

Answer 1

Your first and second line (not counting the def line) are not indented the same amount, but they should be.

Answer 2

pls use a code pasting site

Answer 3

def runSimulation(num_robots, speed, width, height, min_coverage, num_trials,
robot_type):
"""
Runs NUM_TRIALS trials of the simulation and returns the mean number of
time-steps needed to clean the fraction MIN_COVERAGE of the room.

The simulation is run with NUM_ROBOTS robots of type ROBOT_TYPE, each with
speed SPEED, in a room of dimensions WIDTH x HEIGHT.

num_robots: an int (num_robots > 0)
speed: a float (speed > 0)
width: an int (width > 0)
height: an int (height > 0)
min_coverage: a float (0 <= min_coverage <= 1.0)
num_trials: an int (num_trials > 0)
robot_type: class of robot to be instantiated (e.g. Robot or
RandomWalkRobot)
"""
time=0
for trial in range(num_trial):
room=RectangularRoom(width,height)
robot=[]
for ii in range(num_robots):
robot.append(robot_type(room,speed))
while room.getNumCleanedTiles()/room.getNumTiles() < min_coverage:
for ii in range(num_robots):
robot[ii].updatePositionAndClean()
time=time+1

return time/num_trial

Answer 4

Thanks. As above, it still don't work~

Answer 5

time=0
^
IndentationError: unindent does not match any outer indentation level

Answer 6

Like @bwca said, please use a code pasting site so it would be easier for us to see the indentations clearly and help you debug the code :)

Answer 7

How do I do that? I just use the code pasting site to generate it and paste it here again...

Answer 8

@CindyCheng: You paste it on the site, it will give you a link then you paste the link here. Like what I did with your code here :)

And with that, I noticed that your return statement at the end doesn't align with the first 2 lines of the code :)
