PIR sensor Motion Detection count Write to Text File in python -


i need write "pir sensor" motion detection count text file.

i tried code , work without writing text file. when put write file gives error file = open("textfile.txt", "w") indentationerror: unindent not matchanyouter indentation level. expected output last motion count number in text file.

code 

    # import required python libraries     import time     import rpi.gpio gpio     gpio.setmode(gpio.bcm)     # define gpio use on pi     gpio_pir = 7  # set pin input    gpio.setup(gpio_pir,gpio.in)      current_state  = 0  previous_state = 0      # put  variable= 0 motion count  variable= 0        try:                print "waiting pir settle ..."        # loop until pir output 0       while gpio.input(gpio_pir)==1:         current_state  = 0            print "  ready"  # loop until users quits ctrl-c   while true :      # read pir state     current_state = gpio.input(gpio_pir)      if current_state==1 , previous_state==0:       # pir triggered       start_time=time.time()       print "  motion detected!"        # here need write numbers text file.       file = open("textfile.txt", "w")       file.write(variable)       file.close()       variable+=1        # record previous state       previous_state=1     elif current_state==0 , previous_state==1:       # pir has returned ready state       stop_time=time.time()       print "  ready ",       elapsed_time=int(stop_time-start_time)       print " (elapsed time : " + str(elapsed_time) + " secs)"       previous_state=0  except keyboardinterrupt:   print "  quit"   # reset gpio settings   gpio.cleanup() 

import rpi.gpio gpio import time  # use bcm gpio references # instead of physical pin numbers gpio.setmode(gpio.bcm)  # define gpio use on pi gpio_pir = 7  print "pir module test (ctrl-c exit)"  # set pin input gpio.setup(gpio_pir,gpio.in)      # echo  current_state  = 0 previous_state = 0 variable=0   try:    print "waiting pir settle ..."    # loop until pir output 0   while gpio.input(gpio_pir)==1:     current_state  = 0        print "  ready"        # loop until users quits ctrl-c   while true :      # read pir state     current_state = gpio.input(gpio_pir)      if current_state==1 , previous_state==0:       # pir triggered       print "  motion detected!"       # record previous state       previous_state=1       file = open("textfile.txt", "w")       file.write(variable)       file.close()       variable+=1     elif current_state==0 , previous_state==1:       # pir has returned ready state       print "  ready"       previous_state=0      # wait 10 milliseconds     time.sleep(0.01)        except keyboardinterrupt:   print "  quit"   # reset gpio settings

this friend's code. (i believe nothing wrong code few indentation error(e.g. spacing error) can use sort of text editor (i use sublime text)

javascript - RequestAnimationFrame not working when exiting fullscreen switching space on Safari -
