No.

[0] * 5

>     a = [0, 0, 0, 0]

a = [0] * 4

"sequence * int" is defined for all Python sequence types (incl. lists,
arrays, tuples and strings).

Advanced trick of the trade:

    s * 0

can be used to create an empty sequence of the same type as s, without
needing to know s's type.  Slice notation can also be used for that purpose:

    s[:0]  # i.e., one way to ask for an empty slice
