write multiple lines in a file in python

Question

I have the following code: ``` line1 = raw_input("line 1: ") line2 = raw_input("line 2: ") line3 = raw_input("line 3: ") print "I'm going to write these to the file." target.write(line1) target.write("
") target.write(line2) target.write("
") target.write(line3) target.write("
") ``` Here target is the file object and line1, line2, line3 are the user inputs. I want to use only a single target.write() command to write this script. I have tried using the following: ``` target.write("%s 
 %s 
 %s 
") % (line1, line2, line3) ``` But doesn't that put a string inside another string but if I use the following: ``` target.write(%s "
" %s "
" %s "
") % (line1, line2, line3) ``` The Python interpreter(I'm using Microsoft Powershell) says invalid syntax. How would I able to do it?

Accepted Answer

You're confusing the braces. Do it like this:

```
target.write("%s 
 %s 
 %s 
" % (line1, line2, line3))
```

Or even better, use `writelines`:

```
target.writelines([line1, line2, line3])
```
