Using * to create ntuples (unexpected behavior)

Question

Can somebody explain why this creates a list of 5 elements:

['']*5

While this create a tuple of 1 element

('')*5

But this creates a tuple with six elements:

('', '')*3

Question: is there a way to create tuple with an odd number of elements without using a generator (i.e. by using *)?

`('')` isn't tuple. `('',)` is a tuple. – M. Volf Dec 03 '17 at 16:24 — M. Volf, Dec 03 '17 at 16:24

('') is actually not a tuple, it is a string. You want to write ('',).

No problem. Pretty common error. I've made it more than once. :-) – Dec 03 '17 at 16:24
