Python program to convert a list to string

Given a list, write a Python program to convert the given list to string.

There are various situation we might encounter when a list is given and we convert it to string. For example, conversion to string from the list of string or the list of integer.

Example:

Input: ['Geeks', 'for', 'Geeks']
Output: Geeks for Geeks

Input: ['I', 'want', 4, 'apples', 'and', 18, 'bananas']
Output: I want 4 apples and 18 bananas

Let’s see various ways we can convert the list to string.

Method #1:
Iterate through the list and keep adding the element for every index in some empty string.

# 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 = ['Geeks', 'for', 'Geeks'] 
print(listToString(s))  

Output:

GeeksforGeeks

Method #2: Using .join() method

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

Output:

Geeks for Geeks

But what if the list contains both string and integer as its element. In those cases, above code won’t work. We need to convert it to string while adding to string.

Method #3: Using list comprehension

# Python program to convert a list 
# to string using list comprehension 
   
s = ['I', 'want', 4, 'apples', 'and', 18, 'bananas'] 
  
# using list comprehension 
listToStr = ' '.join([str(elem) for elem in s]) 
  
print(listToStr)  

Output:

I want 4 apples and 18 bananas

Method #4: Using map()
Use map() method for mapping str (for converting elements in list to string) with given iterator, the list.

# Python program to convert a list 
# to string using list comprehension 
   
s = ['I', 'want', 4, 'apples', 'and', 18, 'bananas'] 
  
# using list comprehension 
listToStr = ' '.join(map(str, s)) 
  
print(listToStr)  

Output:

I want 4 apples and 18 bananas
