But when I look at performance Python is not near C# or Java
For most websites out there it doesn't matter. Facebook ran on normal PHP (similar performance to Python) up until the point when they had 500 million users and were forced to make some changes.
Instagram and Pinterest are powered by Python. Unless your site is bigger than those, you'll be fine running Python.
And I can't seem the find features of C# in Python
Python has a huge ecosystem of libraries. Maybe you just don't know where to look?
