How to Convert List to String in Python with Examples
Stechies

There are few methods to convert a list to string in python

1. Using join () function

It is basically joining function, which is used to join the two or more strings in python or to concatenate a list of characters can be joined using the join function. 

For example

stng = ""
stng1 = ("gaon", "gore", "Gaon")
print (stng.join(stng1))

Output:

gaongoreGaon

''.join
Convert integer
To convert different type of data to a string use str function.

mlist =[1,2,3]
print''.join(str(e) for e in mlist)

Output:

123

Specifying any type of Delimiters

Till now we have used space as a delimiter, but you can use any type of elements to separate in new string. Here we are using '-' (hyphen).

mlist =['1','2','3']
print'-'.join(str(e) for e in mlist)

Output:

1-2-3

Specify to Some Extent of Range

In some of the cases we are required not to change the whole string but half of string or to some extent, in that case, we specify the range to be changed

Here we are using Range of two elements.

mlist =['1','2','3','4']
print'-'.join(str(e) for e in mlist[:2])

Output: 

1-2

Join(list) - String Method

Using “”.join(list):- it takes a list and join in a string. It is called string method.

Note: If the list contains strings then it joins them.

Example:

m_lst = ["Mumbai ", "is ",  "a city"]
print "".join(m_lst)          ## python 3 does not support it

Output 

Mumbai is a city

Using ''.join(map())

In case of number list another function can map() also can be used to convert into string and join.

m_lst = [90, 88, 65, 64]
print "".join(map(str, m_lst))        ## python 3 does not support it

Output will be

90 88 65 64

2. Traversal of list Function

A list of characters initialize at starting, and traverse to all characters in the list, indexed and all collected to frame a string. As the traverse is completed the string is printed.  

Examples:
# program to convert a list of charcater to a string

def convert(characters): 
    # initialization of string to "" 
    new_char = "" 
    # traverse in the string 
    for x in characters: 
        new_char += x 
    # return string 
    return new_char 
# driver code 
characters = ['I', 'n', 'd', 'i', 'a ', ' i', 's', ' a ', 'g', 'r', 'e', 'a', 't'] 
print(convert(characters))

Output of the program will be

India is a great
