Why do I see two back slashes when I type variable name on python shell ?
>>> print '6\\3=2'
6\3=2 ==> Correctly prints back slash
>>> var1='6\\3=2'
>>> print(var1)
6\3=2 ==> Correctly prints back slash
>>> var1
'6\\3=2' ==> Why do I see two back slashes here ? Instead of just one ?

The output in the python shell is the string representation. It is printed in the same way, as one would type it in the code.
From the docs:
The str() function is meant to return representations of values which are fairly human-readable, while repr() is meant to generate representations which can be read by the interpreter (or will force a SyntaxError if there is no equivalent syntax)
print() calls __str__() on the object, while putting the var var1 in the console just calls the objects internal representation __repr__().
>>> print(var1.__str__())
6\2=1
>>> print(var1.__repr__())
'6\\2=1'
