使用brython-runner。您可以在字符串中运行 Python 代码,并使用自定义回调函数处理标准输出和错误。它使用 Web Worker 中的 Brython 实例运行代码。
<script src="https://cdn.jsdelivr.net/gh/pythonpad/brython-runner/lib/brython-runner.bundle.js"></script>
<script>
const runner = new BrythonRunner({
stdout: {
write(content) {
// Show output messages here.
console.log('StdOut: ' + content);
},
flush() {},
},
stderr: {
write(content) {
// Show error messages here.
console.error('StdErr: ' + content);
},
flush() {},
},
stdin: {
async readline() {
var userInput = prompt();
console.log('Received StdIn: ' + userInput);
return userInput;
},
}
});
runner.runCode('print("hello world")');
</script>

尝试一下:
<body onload="brython()">
<script type="text/python">
from browser import document, window
import traceback
def run(event):
try:
exec(document['code'].value)
except Exception:
error_message=traceback.format_exc()
document['error_message_textarea'].value=error_message
document['run'].bind('click',run)
</script>
<input id='code' value='print(123+"OK")'></input>
<button id='run'>
RUN
</button>
<br>
<textarea id='error_message_textarea' style='color:red;width: 300px; height: 300px;'></textarea>
</body>
