Is there a standardized method to swap two variables in Python?

Question

In Python, I\'ve seen two variable values swapped using this syntax:

left, right = right, left

Is this considered the standard way to swap

Answer 1

I would not say it is a standard way to swap because it will cause some unexpected errors.

nums[i], nums[nums[i] - 1] = nums[nums[i] - 1], nums[i]

nums[i] will be modified first and then affect the second variable nums[nums[i] - 1].
