How to use the pass statement?

Question

I am in the process of learning Python and I have reached the section about the pass statement. The guide I'm using defines it as being a Null statement that is commonly used as a placeholder.

I still don't fully understand what that means though. Can someone show me a simple/basic situation where the pass statement would be used and why it is needed?

Answer 1

as the book said, I only ever use it as a temporary placeholder, ie,

# code that does something to to a variable, var
if var == 2000:
    pass
else:
    var += 1

and then later fill in the scenario where var == 2000
