python-cel 0.1.0

Python bindings for the cel-rust crate

Python CEL

Python CEL are Python bindings for the Common Expression Language (CEL) rust implementation found here. CEL is a language designed to allow non-sandboxed evaluation of expressions and scripts.

Features

• Written in Rust: The underlying library and bindings are written in Rust, which makes it fast and memory-efficient.
• Safe: The Rust implementation is memory-safe and thread-safe.
• Extensible: The library is designed to be easily extensible with custom functions and variables.

Quick Start

Installation

pip install python-cel

Basic Usage

from cel import Context, Program, evaluate_expression

# Quickly evaluate an expression
result = evaluate_expression("1 + 2")
print(result)  # 3

result = evaluate_expression("x + y", variables={"x": 1, "y": 3})
print(result)  # 4

result = evaluate_expression("add_nums(1, 2)", functions={"add_nums": lambda x, y: x + y})
print(result)  # 3

# Manually create a context and program
context = Context()
context.add_variables({"x": 1, "y": 2})
context.add_functions({"add_nums": lambda x, y: x + y})

# OR
context = Context(
    variables={"x": 1, "y": 2},
    functions={"add_nums": lambda x, y: x + y}
)

program = Program("add_nums(x, y)")
result = program.evaluate(context)
print(result)  # 3
