❓ What does [ ::-1 ] do?

❗️ Answer: [::-1] is used to reverse the order of an array or sequence.

🔍 For example:
import array as arr
My_Array=arr.array('i',[1,2,3,4,5])
My_Array[::-1]

Output: array('i', [5, 4, 3, 2, 1])

🌟 [::-1] reprints a reverse copy of an ordered data structure such as an array or list. The original array or list remains unchanged.

For each role except for data analyst where programming is not explicitly required, it’s important to learn a programming language like Python. Knowing SQL is equally as important for all roles.

Data science is the first role that embraces machine learning, and as you’re headging towards AI, you’ll see its subsets like deep learning, reinforcement learning, as well as computer vision and NLP.
