How to Convert String to List and List to String in Python

• 1 Method: Python Convert String to List
• 2 Method: Python Convert List to String

1 Method: Python Convert String to List

Python programming uses the split() function of Python to convert a string to a list.

Let’s know about the split() function of Python.

Definition of python split() function :- The pyhon split() function/method splits a given string into the python list.

Syntax of split() function is :-

string.split(separator, maxsplit)

Return Value from split() :-

The split() breaks the string at the separator and returns a list of strings.

Example 1: Convert String to List in Python Using Split() Function

Let’s look at a simple example where we want to convert a string to a list of words i.e. split it with the separator as white spaces.

text= 'Welcome to python world'

# splits at space
print(text.split())

text2 = 'Welcome, to next, python, world'

# splits at ','
print(text2.split(', '))

# Splitting at ':'
print(text2.split(':'))

Output

 ['Welcome', 'to', 'python', 'world']
 ['Welcome', 'to next', 'python', 'world']
 ['Welcome, to next, python, world']

Note that, convert the list to string in python, use the for loop and join() function.

Example 2: Python split() works when maxsplit is specified

text = 'Welcome, to python, world'

# maxsplit: 2
print(text.split(', ', 2))

# maxsplit: 1
print(text.split(', ', 1))

# maxsplit: 5
print(text.split(', ', 5))

# maxsplit: 0
print(text.split(', ', 0))

Output

 ['Welcome', 'to python', 'world']
 ['Welcome', 'to python, world']
 ['Welcome', 'to python', 'world']
 ['Welcome, to python, world']

2 Method: Python Convert List to String

Example 1: python list to string using for loop

Using the python for loop convert a list to string in python. You can see below the python program to convert the list to string using for loop:

# Python program to convert a list to string 
	
# Function to convert 
def listToString(s): 
	
	# initialize an empty string 
	str1 = "" 
	
	# traverse in the string 
	for ele in s: 
		str1 += ele 
	
	# return string 
	return str1 
		
		
# Driver code	 
s = ['Hello', 'python', 'programmer'] 
print(listToString(s)) 

Output

Hellopythonprogrammer

Example 2: python convert list to string using join

Using the python join() function convert a list to string in python. You can see below the python program to convert the list to string using python join() function:

# Python program to convert a list 
# to string using python join() method 
    
# Function to convert   
def listToString(s):  
    
    # initialize an empty string 
    str1 = " " 
    
    # return string   
    return (str1.join(s)) 
        
        
# Driver code     
s = ['Hello', 'python', 'dev'] 
print(listToString(s)) 

Output

 Hello python dev

Question 1:- In Python, how do I convert a string to a list in which each character will be separated?

Answer :- You can convert string word to list, so you can use list() method in python. See the following example below:

string = 'python'

convertToList = list(string)

print(convertToList)

Output

['p', 'y', 't', 'h', 'o', 'n']
