Python for loop with a more intuitive upper bound? -


sometimes little confusing me keep in mind upperbound for loop excluded default. there way make inclusive?

yes, for in range(upper + 1) or if like, for in range(lower, upper + 1) work,

a lot of programming languages use zero-based indexing, non-inclusive upper bound common practice (this due memory addressing , adding offset)

just example: if had array of size 5, ar, starting index 0, your largest valid index value 4 (i.e., 0, 1, 2, 3, 4), loop construct refer size of array (5) so:

for in range(5):

or more common , better:

for in range(len(ar)):

.. ensuring legal index values 0 .. 4.
