Low quality clickbait. This whole article could've been 2 sentences. Here's the entire article for you: "For lists, += and *= do the operation in place, whereas a=a+b will create a new object and then copy. The former is marginally faster."

It's not quite a copy in the latter case. The assignment operator in Python binds names to objects, so it's more of a relabeling.

  This is misleading. It would indeed be a re label but the original list a would be garbage collected - that can be costly if a was big.
