// Call the jsPython function to get an evaluator object
const evaluator = jsPython();
// Define the Python code you want to evaluate
const codeToEvaluate = `
print("Hello from Python!")
`;
// Evaluate the code and handle the resulting Promise
evaluator.evaluate(codeToEvaluate)
.then(
// This arrow function runs if the evaluation is successful
result => {
console.log('Result =>', result);
},
// This arrow function runs if the evaluation fails
error => {
console.log('Error =>', error);
}
);
Explanation:
jsPython()
: This function is presumed to return an object that can evaluate Python code from within JavaScript.evaluate(codeToEvaluate)
: Pass the Python code (as a string) to theevaluate
method. This returns a Promise..then(...)
: When the Promise settles,.then()
is called.
- The first callback (
result => { ... }
) handles the resolved value, printing out the result. - The second callback (
error => { ... }
) handles any rejected value (errors), printing out the error message.
