Use the string find method described here 
http://docs.python.org/3/library/stdtypes.html#string-methods to get an 
offset for 1700.  Add 6 to it.  Print a slice of 4 characters starting 
from this offset.  If you don't know what slicing is please read the 
appropriate section here 
http://docs.python.org/3/tutorial/introduction.html#strings.
