Python strings are indicated using either the single (') or double (") quotation mark and they are allowed to use one notation within a string delimited by the other:

>>> example = "she loves ' giancarlo"
>>> example
"she loves ' giancarlo"

On multiple lines, they are enclosed in triple (or three single) quotation marks (''' multi-line string '''):

>>> _string_='''I am a 
multi-line 
string'''
>>> _string_
'I am a 
multi-line
string'

Python also supports Unicode; just use the u "This is a unicode string" syntax :

>>> ustring = u"I am unicode string"
>>> ustring
'I am unicode string'

To enter values in a string, type the % operator and a tuple. Then, each % operator is replaced by a tuple element, from left to right:

>>> print ("My name is %s !" % ('Mr. Wolf'))
My name is Mr. Wolf!
