IndentationError：预期缩进的块Analyze（）Python 3

Question

I'm using python and when i call my function it gives me this:

  IndentationError: expected an indented block

Error, this is pretty frustrating because i have checked all the tabs and it looks fine! What is the problem, can anyone help me, it seems like a simple and dumb problem but it is not going away!

Analyze()

At the bottom is the thing highlighted when the error is thrown!

Heres my code (i'm coding a Jarvis AI):

Answer 1

Functions cannot be empty in python. Lines commented out is not valid content.

This will give you an IndentationError:

def test():
    # comment

To solve it you need to add a pass . ("do nothing command")

def test():
    # comment
    pass

One exception is when you have a docstring.

def test2():
    """This is a test"""

here pass is assumed.

Answer 2

Your problem is in def Analyze_for_answer() (line 232)

This function is empty, remove the comments or the function, or add one line with the word 'pass' and the problem will be solved.

Tip: Lower case for functions names
