Why compiled programming languages are usually difficult ?

Question

I've noticed several times that, the programming language that are compiled are relatively more complicated to code/understand than interpreted languages.

Just opposite of that, compiled language are quite easy to debug while interpreted languages are too much difficult to debug.. specially indentation in python and types similarity in JavaScript and it's weird features.

Why interpreters were made? Instead of processing each instructions one by one, the translator should process the whole code into a binary like form...
Why even interpreters exist ? Shouldn't all interpreters transform into a compiler?
Mainly Python

Answer 1

Atleast intepreted programming languages would have been created to fill some weaknesses of compiled languages. Python has more automated memory management unlike in C.

Answer 2

Python has a compiled extension PyPy.
