The Python list can be converted into string by using the following methods. Let’s understand the following methods.

Method - 1

The given string iterates using for loop and adds its element to string variable.

Example -

# List is converting into string  
def convertList(list1):  
    str = ''  # initializing the empty string  
  
    for i in list1: #Iterating and adding the list element to the str variable  
        str += i  
  
    return str  
  
list1 = ["Hello"," My", " Name is ","Devansh"] #passing string   
print(convertList(list1)) # Printin the converted string value

Output:

Hello My Name is Devansh

Method -2 Using .join() method

We can also use the .join() method to convert the list into string.

Example - 2

# List is converting into string  
def convertList(list1):  
    str = ''  # initializing the empty string  
  
    return (str.join()) # return string  
  
list1 = ["Hello"," My", " Name is ","Devansh"] #passing string  
print(convertList(list1)) # Printin the converted string value

Output:

Hello My Name is Devansh

The above method is not recommended when a list contains both string and integer as its element. Use the adding element to string variable in such scenario.

Method - 3

Using list comprehension

# Converting list into string using list comprehension  
list1 = ["Peter", 18, "John", 20, "Dhanuska",26]  
  
convertList = ' '.join([str(e) for e in list1]) #List comprehension  
  
print(convertList)

Output:

Peter 18 John 20 Dhanuska 26

Method - 4

Using map()

# Converting list into string using list comprehension  
list1 = ["Peter", 18, "John", 20, "Dhanuska",26]  
  
convertList = ' '.join(map(str,list1)) # using map funtion  
  
print(convertList)

Output:

Peter 18 John 20 Dhanuska 26
