What does the Star operator mean? [duplicate] 5 answers

With this:

zip(*zipped)

you tell python the same as this:

zip(zipped[0],zipped[1],zipped[2])

for this basic example.

What does exactly that operator

When used as argument of a function, it takes the elements of the argument and expand it before passing as argument.

For instance:

power = [2,3]
math.pow(*power)

Would give you the value of 2³ = 8.
