The Output is [4,5], but why? 🤔

Question

arr=[1,2,3,4,5,6]
print(arr[2:5][1:3])

Output
[4,5]

Answer 1

Once typo corrected to: print(arr[2:5][1:3])
You need to understand Python array slicing:
https://www.pythoncentral.io/how-to-slice-listsarrays-and-tuples-in-python/

array[start index:excluded end index]

arr[2:5] is tmp = [3,4,5]
and then, tmp[1:3] = [4,5]

Answer 2

Yohann
isn't it "print(arr[2:5][1:3])" instead of "print(arr[2:5][1,3])"?

Answer 3

Traceback (most recent call last):
File "..\Playground\", line 2, in <module>
print(arr[2:5][1,3])
TypeError: list indices must be integers or slices, not tuple
you are calling a tuple in another part of the archive, not the array that you have in the code that you wrote, right?
