Python Operators – Exploring New Operators in Python

operator-keywordoperatorspython

We can define intrinsic operators of Python as stated here. Just for curiosity, can we define new operators like $ or ***? (If so, then we can define ternary condition operators or rotate operators.)

As @minitech said you can't define new operators. But check this hack that allows you to define infix operators http://code.activestate.com/recipes/384122-infix-operators/

While technically you cannot define new operators in Python, this clever hack works around this limitation. It allows you to define infix operators like this:

# simple multiplication
x=Infix(lambda x,y: x*y)
print 2 |x| 4
# => 8

# class checking
isa=Infix(lambda x,y: x.__class__==y.__class__)
print [1,2,3] |isa| []
print [1,2,3] <<isa>> []
# => True
