What does zip (*) do in Python?

Python's zip() function is defined as zip(*iterables) . The function takes in iterables as arguments and returns an iterator.

What does zip and * operator do?

The "*" operator unpacks a list and applies it to a function. The zip function takes n lists and creates n-tuple pairs from each element from both lists: zip([iterable, ...]) This function returns a list of tuples, where the i-th tuple contains the i-th element from each of the argument sequences or iterables.

What does the asterisk operator do?

It is used to pass the variable number of parameters to the function, typically non-key arguments and argument lists of varying lengths. There are many applications for it, and one of them is shown in the example below. We create an additional function that can add any number of parameters using the *args keyword.

Which * operator is used to get the address of a variable?

What does * mean in Python function declaration?

Python provides us with a syntax for defining a function, which can be called with an arbitrary number of positional arguments. This is signaled by the syntax def f(*<var_name>) . # The * symbol indicates that an arbitrary number of # arguments can be passed to `args`, when calling `f`.

What is star star operator in Python?

What is single star and double star in Python?

What is star and double star in Python?
