Split a string into array of characters in Python

By IncludeHelp Last updated : February 13, 2024

Problem statement

Given a string, write a Python program to split the given string into array of characters.

Splitting string into array of characters

You can follow the following different approaches to split a string into array of characters:

By using the loop
By converting string to the list

Split string into array of characters using for loop

Use for loop to convert each character into the list and returns the list/array of the characters.

Python program to split string into array of characters using for loop

# Split string using for loop

# function to split string
def split_str(s):
  return [ch for ch in s]

# main code  
string = "Hello world!"

print("string: ", string)
print("split string...")
print(split_str(string))

The output of the above program is:

string:  Hello world!
split string...
['H', 'e', 'l', 'l', 'o', ' ', 'w', 'o', 'r', 'l', 'd', '!']

Split string into array of characters by converting string to the list

We can typecast string to the list using list(string) – it will return a list/array of characters.

Python program to split string into array by typecasting string to list

# Split string by typecasting 
# from string to list

# function to split string
def split_str(s):
  return list(s)

# main code  
string = "Hello world!"

print("string: ", string)
print("split string...")
print(split_str(string))

The output of the above program is:

string:  Hello world!
split string...
['H', 'e', 'l', 'l', 'o', ' ', 'w', 'o', 'r', 'l', 'd', '!']
