from flask import Flask
app = Flask(__name__)

@app.route('/')
def home():
   return 'This is Home!'

if __name__ == '__main__':
   app.run('0.0.0.0',port=5000,debug=True)

위와 같이 코드를 작성하고 터미널을 실행한 결과 5000번 포트를 이미 사용하고 있다고 출력됩니다.

터미널 출력 결과입니다.

해결 방법이 있을까요?

Port 5000 is in use by another program. Either identify and stop that program, or start the server with a different port.
On macOS, try disabling the 'AirPlay Receiver' service from System Preferences -> Sharing.
