[FIXED] How to annotate a function in python that returning an html file

Issue

Here is my code I also tried it without quotes but it gives me ('html' is not defined) error

@app.route('/entry')
def entry_page() -> 'html':
    return render_template('entry.html',
                           the_title='Welcome to searchtools on the web!')
app.run()

Solution

That's not how annotations work -> is a syntax meant to mention the type of data being returned. To annotate functions there are various methods.

Method 1: Commenting (also known as single line comment)

def function(a): # Annotation
    return a

Method 2: String Literal (also known as multi line or docstring comment)

def function(a):
    """
    Returns the value passed
    """
    return a

Method 1 is recommend for small comments (for your case) Method 2 is recommended for big comments
