 Issue: -
 
 ## Description
+Your source code should not contain very long lines. If you have very long lines you should break it up into multiple lines. When code is not easily visible it's difficult to understand what it does. Use the `\` character at the end of a line to tell the Python interpreter that the statement continues on the next line. Here is an example of how to break up a long boolean expression into three lines.
+```python
+  if ( ((blah < 0 ) and (grr > 234)) \ 
+       or ((foo == 3456) and (grr <= 4444)) \
+       or ((blah > 10) and (grr == 3333))  \
+      ): 
+    print "this crazy condition is true"    	
+    print "and my code is really easy to read because"
+    print "I didn't wrap lines!"
 
-Used when a line is longer than a given number of characters.
+  else:
+    print "this crazy condition is false"    	
+```
+By default PEP 8 recommends 79 - 99 characters per line, but we are very liberal so we made it 159 characters per line just for you.
+You can set `max-line-length` in Pylint configuration file depending on your needs.
