With this library, we will use the eval() function to convert a string to a list. This method will use the ast library (Abstract Syntax Trees). The complete example code is as follows: string=""Ĭonvert String to List in Python Using the ast Method Let’s take a specified string for this method. We could use split() or ast methods instead of this. If it couldn’t be evaluated as a Python expression, it will generate an error. This method will only convert the string into a list when the string is safe it means that the string in the eval() function is parsed and determined as a Python expression. Convert String to List in Python Using the eval() Function If the delimiter is not given, it uses the white space as the default value. The above example splits the string at the given delimiter,, to a list. The complete example code is as follows: string='x,y,z' Now we split the string values into the list elements. Let’s take a string in comma-separated values. Convert String to List in Python Using the split() Method Every character in the string becomes the individual element in the list. The list() function takes a string as an argument and converts it into a list. Let’s take the below code as an example: test_str="Python" The list() function converts the string into a list in Python. To convert a space-separated string of integers to a list in Python: Split the string on empty spaces. How to Convert Space-Separated String of Integers to a List in Python. Convert String to List in Python Using the list() Function Let’s then take a look at how to split a string of integers into a list of integers. Python program to convert a list of strings with a delimiter to a list of tuple. In this article, we will demonstrate different methods to convert a string into a list in Python. Python - Convert String List to Key-Value List dictionary. The string is a combination of characters enclosed in single or double quotes, and it is not mutable. Python list is mutable so that its elements can be overwritten, modified, and deleted at any time during the program execution. Convert String to List in Python Using the ast Method.Convert String to List in Python Using the eval() Function.Convert String to List in Python Using the split() Method.Convert String to List in Python Using the list() Function.We learned also how to solve sequence item 2: expected str instance, int found issue.Created: November-09, 2020 | Updated: December-10, 2020 Today we learned how to convert a list to a string by using two methods. converting the list to string by using join() Conclusion My_list_2 = Īs you see in the example, we have 2 lists my_list_1 and my_list_2, and to convert these lists to a string we:Ģ. In this part of tutorial, we'll convert two lists to astring by using join(). Output Advertisements Convert Two lists to a string To solve this issue, we need first convert the list's items to the string, then convert the list to string. Convert a list contains an int to stringĪs I said, when you try to convert a list that contains an integer, we'll get sequence item 2: expected str instance, int found. To solve this issue, let's see how to convert a list contains an int to string. In our list, we have two different data type. If the delimiter is not specified in the function argument or is None, then a. Then, it returns a list of the words in the string, using the delimiter as the delimiter string. The split () is a built-in Python method that splits the strings and stores them in the list. Generally, in programming languages, we can't join or concatenate the data that have a different type of data. To convert string to list in Python, use the string split () method. To answer this question, let's try to convert a list that contains an integer. To understand, let's see the following example.īut if your list contains one or more integers, does this method work? In this method #2, we'll use join() function. To print the string with spaces, we need to use format format(). adding the list's items to the empty variable my_list. In the first method, we'll onvert alist to string without using any built-function. Conclusion Converting a list to string (method #1)
