Python Escape Characters

In String literals, we can use escape characters to associate a special meaning.

>>> s="mohan\nsoftware" 
>>> print(s) 
mohan
software 
>>> s="mohan\tsoftware" 
>>> print(s) 
mohan software 
>>> s="This is " symbol" 
File "<stdin>", line 1 
s="This is " symbol" 
 ^ 
SyntaxError: invalid syntax 
>>> s="This is \" symbol" 
>>> print(s)
