Python provides a map()function that you can use to apply a specific function to all given elements in any specified iterable object. This function returns an iterator itself as output. Mapping objects can also be converted into sequence objects such as tuples and lists using their own factory functions.

This tutorial will discuss and demonstrate different methods that can be used to convert a Map object to a list in Python.

list()Use the method to convert a Map object into a list in Python

Lists are a part of the four built-in data types provided in Python and can be used to store multiple items in a single variable. Lists are ordered, mutable, and have a definite number of items.

list()The function is used to create a list object in Python. This method is used to convert a specific tuple into a list. The following code uses list()the method to convert a Map object into a list in Python:

a = list(map(chr, [70, 50, 10, 96]))
print(a)

Output:

['F', '2', '\n', '`']

In Python 3, many operations or processes performed on iterators return the iterators themselves; this further simplifies the language. This also leads to better and more efficient programs.

Convert Map object to list using list comprehension in Python

List comprehension method is a relatively short and very elegant way to create a list from the given values ​​of an existing list. This method can be used in this case and create a list from a Map object by simple iteration.

The following program uses this method to convert a Map object to a list in Python:

a = [chr(i) for i in [70, 50, 10, 96]]
print(a)

Output:

['F', '2', '\n', '`']

*Converting Map Objects to Lists Using Iterable Unpacking Operators in Python

In Python, the term 解包can be defined as an operation whose main purpose is to assign an iterable object with all the values ​​to a list or tuple, provided it is done in a single assignment statement.

The star *symbol is used as iterable unpacking operator. Iterable unpacking operator works well and efficiently on tuples and lists.

The following code uses the iterable unpacking operator *to convert a Map object to a list in Python:

a = [*map(chr, [70, 50, 10, 96])]
print(a)

Output:

['F', '2', '\n', '`']

In most cases, this method is more efficient than the other two. Still, the margins as the iterable unpacking operator is very small, and *the method is shorter than one character in a list comprehension. All three methods work well, and you can use any of these methods in regular, everyday programming.
