In this quick Python tutorial, you will learn how to turn a list into a string.How to Convert List to String Python?A list in python is a built-in data type and it’s like an array that contains similar data types values as well as different data types values.Here are the requirements is to convert list elements to a single string.Let see with a coding example.Given Task:input: [‘Learn’, ‘coding ‘,’from’,’LetsTacle’] without space between strings output: “learncodingfromLetsTacle” with delimiter such as space,#,!,@,* etc between strings output: “Learn coding from LetsTacle” output: “Learn#coding#from#LetsTacle” For this, we can make use of multiple methods in python.Method 1: Simple Concatenation | Python List to StringLet’s start with the very basic method of concatenation using a for loop for iterating list elements one by one and concatenating them to the result string, here our required result is in string str1. #method 1 simple concatenation input_list=[ ‘learn’, ‘coding’,’from’,’LetsTacle’] str1 = ” for val in input_list: str1 += val print(str1) Output:learncodingfromLetsTacle Method 2: Using .join() Method Convert List to StringThe join() method takes all items in an iterable and joins them into one string. #method 2 Using .join() method input_list=[ ‘learn’, ‘coding’,’from’,’LetsTacle’] str2=” print(str2.join(input_list)) Output:learncodingfromLetsTacle Method 3: Using map() to Turn a List Into a String | PythonHere we have used the inbuilt map() function, map() loops over the items of an input iterable and returns an iterator that results from applying a transformation function to every item in the original input iterable.For example, below is the syntax for map() in Python:map(function, iterable[, iterable1, iterable2,…, iterableN])In our case, iterable is the input_list and we are converting each element to string type by str function. #method 3 Using map() input_list=[ ‘learn’, ‘coding’,’from’,’LetsTacle’] str3 = ”.join(map(str,input_list)) print(str3) Output:learncodingfromLetsTacle Method 4: Using list Comprehension | Python List to StringList comprehensions are used for creating new lists from other iterable like tuples, strings, arrays, lists, etc. A list comprehension consists of brackets containing the expression, which is executed for each element along with the for loop to iterate over each element.In our case, iterable is input_listSyntax for – List ComprehensionnewList=[function/expression(element) for element in input_list if condition]Here we are iterating element by element and converting them to string and saving in the list, at the end we have used join() on a new list to result in the required output string. #method 4 Using list comprehension input_list=[ ‘learn’, ‘coding’,’from’,’LetsTacle’] str4 = ”.join([str(val) for val in input_list]) print(str4) Output:learncodingfromLetsTacle Note: What if we want some delimiter in between the string while the list gets converted. Delimiter such as space, #,! @, * etc between stringsExample 1: For space in between the String input_list=[ ‘learn’, ‘coding’,’from’,’LetsTacle’] str1 = ” #adding space delimiter before concatination for val in input_list: str1 += ” “+val print(str1) Output:learn coding from LetsTacleExample 2: For * in between the String input_list=[ ‘learn’, ‘coding’,’from’,’LetsTacle’] str2=”*” #give delimiter such as space,#,!,@, etc print(str2.join(input_list)) Output:learn*coding*from*LetsTacleExample 3: For @ in between the String input_list=[ ‘learn’, ‘coding’,’from’,’LetsTacle’] #give delimiter such as space,#,!,@,* etc str3 = ‘@’.join(map(str,input_list)) print(str3) Output:learn@coding@from@LetsTacleYou can use any of the methods shown and use your desired delimiter in between the string.Like this article? Follow us on Facebook and LinkedIn.
