RE: Using the map function in Python
I came across the `map()` function in a Python script and I'm struggling to understand how it works and when to use it. Can someone provide a breakdown of its usage?
The `map()` function in Python allows you to apply a function to every item in an iterable (like a list or tuple) and returns a map object which can be converted into a list or other iterable. This can be useful when you need to perform the same operation on every item of a list.

`map(function, iterable)`

def multiply_by_two(x):
return x * 2
my_list = [1, 2, 3, 4, 5]
result = map(multiply_by_two, my_list)
```
Immediately after using `map()`, result is a map object: `
