how am i going to change the filename automaticaly?
for example:
#every 5 minutes, i am going to create a file based on the data above
for i in range(100)
output_file = file('c:/output' +.join(i) +'.txt', 'w')
#guess this won't work
output_file.writelines(lines)
output_file.close()
When faced with this problem, one of the tings that I liked to do was use a date stamp for the files. The time module has a function called strftime which allows you to use a template to create a string from the current time. (See the documentation of python module 'time' for more details.) e.g.
###
>>> import time
>>> time.strftime('%Y%m%d%H%M')
'200503150934'
###This string can be added to your 'c:/output' rather than a generic number like i. Just to be safe you might want to check that the file doesn't already exist. The nice thing is that there should be few files that have this number added to them so the loop to get a valid name is going to succeed quickly.
