Let's start with you telling me what you understand about packing/unpacking.

packing is like compressing multiple values in single variable without any distortion in values, and unpacking is getting out individual variables from dict or list or single compressed variable

it is really honer to learn from you kenneth. You are one of my favourite teachers.

OK, that's a pretty good start.

packing is like compressing multiple values in single variable

Yep, when we pack values that's exactly what we're doing.

When we unpack values, we take them from an iterable and turn them into either new variables or key/value pairs.

a, b, c = (1, 2, 3)

This unpacks the (1, 2, 3) tuple into the variables a, b, and c.

**{"name": "Kenneth", "language": "Python"}

This would unpack the dictionary into the key/value pair name="Kenneth", language="Python", like we would use as the arguments to a function.
