Your question is Swap Two Numbers in Python. Start with the requirements on the right.
Run and submit as often as you like. When you're ready, talk me through your approach or go straight to the code.
DXC Technology engineers often write small Python utilities that transform values before passing them between application services. Implement a function that swaps two integer values without changing either input variable outside the function.
Given two integers a and b, return a two-element list containing the values in swapped order. The first output element must be the original value of b, and the second must be the original value of a.
Do not perform arithmetic-based swapping, such as addition and subtraction. Use Python's assignment features or another clear constant-space technique.
