Python中类似C的结构数组

Question

How can i implement a C like struct,create an array of such a struct and read such data in Python?

typedef struct Pair{
int first_element,second_element;
}Pair;


Pair array_of_pairs[10];

Answer 1

Python arrays can contain anything - and they grow as needed so you don't need to put a hard-limit on the size.

Try this - it creates a namedtuple (good way to represent struct like things).

from collection import namedtuple
Pair = namedtuple("Pair", ["first", "second"])

p1 = Pair(1,2)
p2 = Pair(3,4)

list_of_pairs = [p1,p2]

print(list_of_pairs)

Answer 2

Use tuples:

pair = (1, 2)
first, second = pair
array_of_pair = [pair, (3, 4)]
