Answer 1

That error simply means that it expected an indented block for some kind of statement and there wasn't one. For instance:

x=5
if (x==5):
print("hi")

In your case, it's probably something like this.

x=5
if (x==5):
print("hi")

In a lot of languages, indentations don't matter too much (with the exception of case) because they rely on brackets. But, in python, it mostly relies on indentation so you'll need to look out for that.
