Swap Variable

Sourcery refactoring id: swap-variable

Description:

Swap variable values with tuple assignment

Before:

temp = a
a = b
b = temp

After:

a, b = b, a

Explanation:

When trying to swap the values held by two variables, we may avoid using an extra temporary variable unnecessarily by employing Python's tuple assignment. As a consequence of this refactoring, the code is not only more concise but also reflects its intention more clearly.
