Convert a List into a String in Python

In this tutorial, we will learn how to convert a list into a string in Python.

A list is a collection of elements that are mutable and ordered. ( Learn: What are the Mutable and Immutable objects in Python? )

The term mutable means that the elements may be modified.

There are different methods to convert list into a string. Let’s see one by one.

Creating a List: Convert a List into a String in Python

l = ["pavan" , "jagan" , "venkat" , 1, 2, 3.9] 

print (l)

print (type(l))

Output :

['pavan', 'jagan', 'venkat', 1, 2, 3.9]
<class 'list'>

Method 1: Iterative

Using the Iterative method to convert every element in the list to add into a string.

def convert_to_string (l):    # naive method
    string = ""
    for i in l:
        string += i
    return string



l = ["pavan" , "jagan" , "venkat"] 

print (convert_to_string(l))

Output :

pavanjaganvenkat

Method 2: list into a string

Certainly, the conversion could be done in a single line.

Therefore, List Comprehension technique with the ” .join ” function can be used to convert a list into a string.

l = ["Achievers", "pavan" , "jagan" , "venkat" , "bhanu"] 

con_str = ' ' .join( [ str(i) for i in l] )  # using .join and list comprehension

print (con_str)

Output :

Achievers pavan jagan venkat bhanu

Method 3: list to string in Python

In contrast, to the above methods, a higher-order function can be used like map.

Probably, the below example is likely to clear the concept.

l = ["bhanu" , "surya" , "bolla" , "sairam"]  # a list

con_str = ' ' .join (map(str,l))  # using .join and map( function , sequence)

print (con_str)

Output :

bhanu surya bolla sairam

 

Concluding the topic, even if the list is most flexible there would be some requirements to convert them.

Moreover, the above methods help to convert them and use other sequences also.
