Defining Custom Operators in Python

While Python does not inherently support custom operator definitions, there exists a workaround that allows you to create and utilize them.

Infix Operators

Infix operators are those that appear between operands, like , *, and ==. To define an infix operator, you can use the Infix class:

x = Infix(lambda x, y: x * y)

This will create an operator |x| that performs the given operation. For example:

print(2 |x| 4) # Output: 8

Other Custom Operators

You can also define prefix, postfix, circumfix, and non-associative infix operators. Here are some examples:

Prefix

inc = Prefix(lambda x: x   1)
print(inc(1)) # Output: 2

Postfix

negate = Postfix(lambda x: -x)
print(10 negate()) # Output: -10

Circumfix

greater_than = Circumfix(lambda x, y: x > y)
print(2 greater_than 1) # Output: True

Non-Associative Infix

xor = Infix(lambda x, y: x ^ y)
print(1 xor 2 xor 3) # Output: 0 (not 7)

By utilizing these techniques, you can extend Python's functionality and create custom operators tailored to your specific requirements.
