Hello,
I have a python 2D array that looks like this:

Labels = ["A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", \
    "M", "N", "O", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z", \
    "AA", "BB", "CC", "DD", "EE", "FF", "GG", "HH", "II", "JJ", "KK", "LL", \
    "MM", "NN"]

Load = [0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
             0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
             0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
             0, 0, 0, 0, 0, 0, 0, 0, 0, 0]

Array = [Labels, Load]

print(Array)
[['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z', 'AA', 'BB', 'CC', 'DD', 'EE', 'FF', 'GG', 'HH', 'II', 'JJ', 'KK', 'LL', 'MM', 'NN'], [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]]

type(Array)
Out[11]: list

I would like to select the element corresponding to the value "A", but how? of course:

Error:
Array["A", 0]
Traceback (most recent call last):

  File "<ipython-input-14-1b9f724cd495>", line 1, in <module>
    Array["A", 0]

TypeError: list indices must be integers or slices, not tuple

`
Is there a way in pure Python, without Numpy or other apps?
Thank you


In [

If you need do it many times, then using dict instead list:

A = dict(zip(Labels, Load))
print(A)

Output:
{'A': 0, 'B': 0, ......}

A['A']

Output:
0

AlekseyPython's code is correct, however might be a bit confusing with the dictionary named the same as one of it's elements,

Easier to understand if:

zipped_dict = dict(zip(Labels, Load))
print(f"zipped_dict element 'A' = {zipped_dict['A']}")
