Question

What does the Double Star operator mean in Python?

Answer 1

For numeric data types double asterisk (**) is defined as exponentiation operator

>>> a=10; b=2

>>> a**b

100

>>> a=1.5; b=2.5

>>> a**b

2.7556759606310752

>>> a=3+2j

>>> b=3+5j

>>> a**b

In a function definition, argument with double asterisks as prefix helps in sending multiple keyword arguments to it from calling environment

>>> def function(**arg):

for i in arg:

print (i,arg[i])

>>> function(a=1, b=2, c=3, d=4)

a 1

b 2

c 3

d 4

We use the name kwargs with the double star. The reason is because the double star allows us to pass through keyword arguments (and any number of them). A keyword argument is where you provide a name to the variable as you pass it into the function.
