Python list() Function

Last updated on August 8, 2022

In this tutorial, you will learn about the Python list() function with the help of examples.

The list() function creates a list object. And a list object is a collection that is ordered and changeable.

You can use the list() function to convert other sequences or iterator objects to a list.

The list() function creates an empty list if no argument is given to the function.

The syntax of the list() function looks like this:

list([iterable])

list() argument may be a sequence, collection or an iterator object. The bracket tells us that the argument passed to it is optional.

Examples:

my_tuple = (4,3,5,0,1)      # define a tuple
my_string = 'hello world!'   # define a string
my_dict = {'name':"Eyong","age":30,"gender":"Male"}  # define a dict

print("tuple to list: ", list(my_tuple)) # Output: tuple to list:  [4, 3, 5, 0, 1]
print("string to list: ", list(my_string)) # Output: string to list:  ['h', 'e', 'l', 'l', 'o', ' ', 'w', 'o', 'r', 'l', 'd', '!']
print("dict to list: ", list(my_dict)) # Output: dict to list:  ['name', 'age', 'gender']
print("empty list: ", list()) # Output: empty list:  []
