The following table illustrates the different assignment statement forms in Python, and their syntax patterns.
| Operation | Interpretation |
|---|---|
| test = 'Test' | Basic form |
| test, ham = 'yum', 'YUM' | Tuple assignment (positional) |
| [test, ham] = ['yum', 'YUM'] | List assignment (positional) |
| a, b, c, d = 'test' | Sequence assignment, generalized |
| a, *b = 'test' | Extended sequence unpacking (Python 3.X) |
| test = ham = 'test' | Multiple-target assignment |
| tests += 42 | Augmented assignment (equivalent to tests = tests + 42) |
The first form is the most common.
The other forms are all optional.
