These are part of the collections module and act very similar to regular tuples
The main difference being that values stored in a named tuple can be accessed using field names instead of indexes.
For example, a point in the two-dimensional plane can be represented using two coordinates. In a regular tuple, these values would be accessed by index ([0] and [1]), but if we define a named tuple, Point, we can access them using x and y instead (although we can still use indexes, too, if we want):
Example:
from collections import namedtuple
# Regular tuple p = (2, 4) # p[0] = 2, p[1] = 4
# Named tuple Point = namedtuple('Point', 'x y') q = Point(3, 5) # q.x = 3, q.y = 5

The SSE was the first modern stock exchange to open in China, with trading commencing in 1990.

The SEE has two trading boards, the Main Board and the Science and Technology Innovation Board, the latter more commonly known as the STAR Market. The Main Board mainly hosts large, well-established Chinese companies and lists both A-shares and B-shares.
