cannot pass variable with url_for flask, python, html5

Question

I was trying to put a link in some text through url_for (flask, python3) and also pass a variable but nothing I tried worked .Here's the code I used. Am I doing something wrong? html5:

<a class="mr-2" href={{ url_for('user','username'=posts.author)}} >TEXT</a>

python3:

@app.route('/user')
def user(username):
    print(username)

You'd need to change the template code to look like:

<a class="mr-2" href="{{ url_for('user',username=posts.author) }}" >TEXT</a>

However you'd also have to change the python code for this to be valid:

@app.route('/user/<username>')
def user(username):
    print(username)

A valid request is now:

/user/CodEdo

Which is the URL which should be rendered in the href assuming that posts.author in the template is CodEdo.
