Is learning Django without initial knowledge of Python possible?
No.  You'll be writing Python code.  In Python.   You'll have to learn Python.
A little bit of your project will be CSS, JavaScript and HTML with template tags inserted.
Most of your project will be Python.
I am coming from procedural PHP with fair amount of knowledge on it. I want to learn Django but I don't have initial knowledge of Python. Can I learn Django at the same time also learning Python? Thank you so much!
