How to Convert Python String to List of Characters

When you are working on a project, you come across a task in which you have to create the characters of a list based on the string. You can create a list based on an input string from either an API or a processed string.

Python String to List of Characters

To convert a string to list of characters in Python, use the list() method to typecast the string into a list. The list() constructor builds a list directly from an iterable, and since the string is iterable, you can construct a list from it.

def stringToList(data):
   return list(data)

data = 'SPIDER-MAN'


['S', 'P', 'I', 'D', 'E', 'R', '-', 'M', 'A', 'N']

We applied a list() function on a string, and it returns a list of all the characters present in the string in the same order as the string’s characters.

The SPIDER-MAN string becomes an individual element of the list, and it preserves the order of the string.

Using List comprehension

List comprehension in Python is frequently used to create a new list, where each list item is the result of some operation applied to each member of a string. You can take any iterable as an input, returning the list.

The list comprehension helps us to convert each character into a list. In addition, list comprehension delivers a shorter syntax when you create a new list based on the existing values.

def stringToList(data):
 return [char for char in data]

data = 'NO WAY HOME'


['N', 'O', ' ', 'W', 'A', 'Y', ' ', 'H', 'O', 'M', 'E']

In this example, the string has some spaces. That’s why we got a list with empty elements. Be aware that any spaces in the line will be included in this list cause they will cause an unexpected output or error.
