We feel that in not "getting" the difference between the two types we
may be missing out on using these data structures to their full
potential.
A crude simplification would be:
- A Python programmer will use a tuple where a C programmer will use a
struct.
- Python and C programmers use lists and arrays similarly.
Tuples are used for passing arguments to and from a function. Common
use of tuples include multiple return values and optional arguments
(*args).
It has already been mentioned that tuples are immutable and can be
used as dictionary keys.
I think collections.namedtuple, introduced in Python 2.6, might help
bridge the gap between a traditional tuple and a C struct.
