Question

I normally use the python shell to test small things, with no needed to make a new .py file.

I wanted to test something like:

>>> def a : 
     pass

but i don’t know how to scape the intro. I tried on the same line

>>> def a: pass

but throws a syntax error, for the indentation I suppose

Answer 1

The syntax for a single-line function definition is:

def a(): pass

You were missing the non-optional () (e.g def a(arg1, arg2): pass)
