It's actually not to do with 1-line blocks, just attempting to define 2
functions "at once":
22:27:23 C:\>python
Python 3.8.3 (tags/v3.8.3:6f8c832, May 13 2020, 22:20:19) [MSC v.1925 32
bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> def f():
... return 42
... def g():
File "<stdin>", line 3
def g():
^
SyntaxError: invalid syntax
>>>
But you are right that adding a blank line after the first function
definition solves the "problem".
