[Python]how to get the item in an mixed array?

Question

here is my code inPython3
from array import array
scores=array('d')
scores.append(97)
scores.append(98)
print(scores[0])

the result will be 97.0
and for scores[1]will be 98.0

then how can I print the str 'd'

Answer 1

'd' isn't an item in the array, it is the typecode for the array ('d': double). `scores.typecode` would get it but if you want 'd' to be an item you might as well use a normal list as it can store multiple types ['d', 97, 98]

Answer 2

array.itemsize is the number of bytes reserved for each array element (this depends on the type)

You can use array.buffer_info() to retrieve the memory address and the total count of elements.
See more in standard docs:
https://docs.python.org/3/library/array.html

In Python we typically use lists instead of array, they are much easier to handle. You may only want to use array if you have to deal with low level programming and C interfaces.

Answer 3

thx a lot. and when I use scores.itemsize get 8, but scores.append some other items the itemsize is still 8.
is the itemsize like len(list), to count the items in an array?
