Error: flask: TypeError: 'function' object is not iterable

Error:
TypeError: 'function' object is not iterable
TypeError: means 'function' object is not iterable
This is what I'm learningIn the html template of flask, there is a missing () when the for loop traverses the flash message, resulting in the traversal object being a function;
Error code:

{% for messages in get_flashed_messages %}{{ messages}}{% endfor %}

Edit to:

{% formessages in get_flashed_messages() %}{{ messages }}{% endfor %}
