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 know three ways to swap variables, but a, b = b, a is the simplest. There is

XOR (for integers)

x = x ^ y
y = y ^ x
x = x ^ y

Or concisely,

x ^= y
y ^= x
x ^= y

Temporary variable

w = x
x = y
y = w
del w

Tuple swap

x, y = y, x
