[Tutor] How to write string in a file, each one on new line???
Folks, I dont like to swamp your mailboxes with my trivial questions. But please tell me why this isnt working?? str = str + '\n' fd.write(str) # fd is teh file handle the traceback is as under: Traceback (most recent call last): File scrap.py, line 39, in ? fd.write(str + '\n')IOError: (0, 'Error') -- To HIM you shall return. ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

But there is no need to swamp our mailboxes by asking the same question more than once, and if you include complete code and complete error tracebacks you have a much better chance of getting a good answer.

Re: [Tutor] How to write this to a file?
print outputs the string to the std output (sys.stdout). You could redirect the std output to a file instead of the screen as follows, but it's a bit clumsy. fptr = open(hans.log, a+) import sys sys.stdout = fptr print Hi there This will output the string into the file hans.log. However, to get it to print to the screen again, u will need to have stored the original contents of sys.stdout somewhere and then redirected sys.stdout to that again. TCL provides a more handy way of doing this: print $fptr Hi there Cheers Hans -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Dick Moores Sent: Thursday, 6 October 2005 12:18 p.m. To: tutor@python.org Subject: [Tutor] How to write this to a file? I have a script that writes it's output to a file.

The formatting part of the print is just an expression with a string value, you can assign it to a variable and write it to your file. You might want to add a newline: timeMsg = Time was %.4g seconds\n % (timeEnd - timeStart) f.write(timeMsg) If you have a lot of output that you want to put to the console and to a log file you might like to look at the logging module. A single line of logging can be written to multiple places by the module. Kent ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
