Python built-in Method - list()

In Python, the list() function is a built-in method that creates a new list object. It takes an iterable as an argument and returns a new list that contains all the elements of the iterable.

The syntax for list() is simple:

list(iterable)

Here, iterable is the iterable object that we want to convert into a list.

For example:

my_tuple = (1, 2, 3, 4, 5)
my_list = list(my_tuple)
print(my_list)    # [1, 2, 3, 4, 5]

In the example above, we create a tuple my_tuple and then use the list() function to convert it into a list my_list.

The list() function is useful when you want to create a new list from an existing iterable, such as a tuple, a set, a dictionary, or even a string. It is often used in conjunction with other methods that return iterables, such as range() or map().

Note that the list() function creates a shallow copy of the iterable. This means that if the iterable contains mutable objects, such as lists or dictionaries, the new list will contain references to those same objects, not copies of them. Therefore, any changes made to those mutable objects will be reflected in both the original iterable and the new list. To create a deep copy of the iterable, you can use the copy module or write your own code to create a new list with copies of all the objects.
