END in file after f.write ?!

[ljmetzger]

My speculation is that '\nEND' is part of one of your variables since you provided incomplete code.

See the following code example:

# write log entry
output = "uuuuu"
f = open("aaa.txt","a")
f.write("\n" +  "xxx " + str(output[-1]))
f.close()
 
print "wrote log"

Output:
xxx u
xxx u
xxx u
xxx u

When you have a problem like this, one of the easiest ways to solve the problem is to start with something that is known to work, and then start adding additional items one at a time. Don't be afraid to write lots of extra things either to the log file or the the screen with a 'print' statement as debugging/diagnostic tools.
