我在打开

"""execute the TraCI control loop"""
traci.init(PORT)#

while traci.simulation.getMinExpectedNumber() > 0:#
traci.simulationStep()#
programPointer = min(programPointer+1, len(PROGRAM)-1)
no = traci.inductionloop.getLastStepVehicleNumber("0")#"0" is the detector id
if no > 0:#
programPointer = (0 if programPointer == len(PROGRAM)-1 else 3)
traci.trafficlights.setRedYellowGreenState("0", PROGRAM[programPointer])#

Python将制表符视为8个空格,但许多文本编辑器将它们视为4. 从不混合制表符和空格。标准是使用四个空格,而不是标签。
除了这两行外,你在每一行都使用了空格:
with open("harsh1.txt","w") as harsh1:
print >> harsh1, """hello"""
这些行缩进了标签。用空格替换它们。
