Using the Pipe in python as an operator

using_pipes.py

# Example of using custom | operations

# Lets say we want to emulate LCEL, a language that uses | as a pipe operator
# For this example we will start with an input which is a dictionary
# and we want our operator object to read the 'input' key and add a new key 'output'

# Our starting data
input_data = {'input': "Hello World"}

# Our operator object that reverses the input and stores it in the 'output' key
class OurCustomOperator:
    def __ror__(self, data):
        data['output'] = data['input'][::-1]
        return data

# Our pipe operator
custom_pipe = OurCustomOperator()

# Now we can use the | operator to apply the custom_pipe to the input_data
print("Starting data:", input_data)
print("Result:", input_data | custom_pipe)

# The result of running this code is the following
"""
Starting data: {'input': 'Hello World'}
Result: {'input': 'Hello World', 'output': 'dlroW olleH'}
