You need to use it when your are not inside some context that makes it
clear to Python that there's more to the line:
You don't need it here because python knows you are inside a list (same is
true for tuple).
a=[1,
2,
3
]
Same for a dictionary:
a={'a1': 1,
'a2': 2,
'a3': 3
}
Also when you are inside call list of a function
a=foo(a,"this is a very long string",
arg3, arg4,
kwarg1='one', kwarg2='two')
Python knows you aren't done because you haven't provided the closing
parenthesis.
I do this in list comprehensions also:
n=[(variable1, variable2) for variable1, variable2 in something
if variable1.startswith('z')]
You do need it in your first example, but not in your second.
