Creating A Namedtuple From A List

Consider a list variable t In [55]: t Out[55]: ['1.423', '0.046', '98.521', '0.010', '0.000', '0.000', '5814251520.0', '769945600.0', '18775908352.0', '2.45024350208e+11

Solution 1:

Use Point(*t) to expand the contents of t as arguments to the Point constructor.

Solution 2:

More efficient solution: Use the special _make alternate constructor to directly construct the namedtuple from an arbitrary iterable without creating additional intermediate tuples (as star-unpacking to the main constructor requires). Runs faster, less memory churn:

Point._make(t)

Despite the name, _makeis part of the public API; it's named with a leading underscore to avoid conflicts with field names (which aren't allowed to begin with an underscore).
