Flask app return string doesn't display <abc>

I tried to display a string on a webpage with this Flask code:

@app.route('/')
def index():
    return 'Variable can be of different types: string and <int>'

and got

Variable can be of different types: string and

without "<>". A way to fix it is to add a space between "<" and "int" like:

Variable can be of different types: string and < int >.

Also I noticed that the space for the closing > as in "< int>" doesn't matter.

Other characters such as [int] and {int} have no such a problem. Why? tag related?

Solution

  • Yes, it is tags related, it gonna be shows up like this

    enter image description here

    If you use the less than (<) or greater than (>) signs in your text, the browser might mix them with tags.

    However, if you want to still display that, you can just do this enter image description here
