Programming Languages for making wordpress-like(blog) website

I was assigned to make a website which is like a blog, so that future or past posts can be edited easily by people managing it in the future. So it will be something like wordpress, and needs to have an admin/dashboard page for setting up the website easily. Also I need enter image description here to implement something like this when editing the posts.

Note that I am required to make it from scratch. I have 2 language in my mind; python(django framework) and PHP. Is there any other I should consider?

What are the cons and pros of using this language for this website?

Thanks!
