### 🚀 **[Create lambda function using chalice](#-Create-lambda-function-using-chalice)**
- `app.py`
```
from chalice import Chalice
import threading
import time
from datetime import datetime
app = Chalice(app_name='multithread-test')
app.debug = True
def run_thread(msg):
app.log.debug(f"Call {msg} and sleep, timestamp {datetime.now()}")
time.sleep(5)
@app.lambda_function(name='multithread-test')
def handler(event, context):
thread_list = list()
for i in range(0, 5):
msg = f'thread-{i}'
thread = threading.Thread(target=run_thread, args=(msg,))
thread_list.append(thread)
thread.start()
for t in thread_list:
t.join()
return "Done!"
```
- Create AWS chalice new project
```
⚡ $ chalice new-project multithread-test
