If you want to track how many time "open_try.py" has been run, you should put the following lines at the beginning of "open_try.py":
counterfilename = 'open_try.count'
try:
file=open(counterfilename,'r')
counter = int(file.readline())
file.close()
counter += 1
file = open(counterfilename,'w+b')
file.write(str(counter))
file.close()
except:
open(counterfilename,'w+b').write('0')
Then, each time you run open_try.py, the counter in open_try.count will be incremented.
It could be done in a more elegant manner, but this will work.
