Using Python's List class to perform a String to List conversion

It's possible that we'll need to change a string into a list in Python while we're writing some code. That could be due to anything else. However, this raises the question, how can a string be converted into various types of lists?

So, let's learn how to do that in Python by converting a string into a list in this tutorial.

Strategies for changing Python strings into lists

In Python, it's not hard to change the format of a string into a list. Depending on our needs, we can employ a variety of approaches to make this happen.

In this guide, we'll explore all the ways we can transform a string into a list in Python. The various approaches are detailed below:

  • List of Strings Given a String
  • String to Character Set Conversion
  • String Mappings to Linked Lists
  • From a Spreadsheet to a List
  • Convert a string of integers to a List of integers.

Let's break down each of those methods we listed above.

1. List of Strings from a String

Python's list.from_separator() method is used to convert a string into a list of the substrings that make up the parent string, with the previous separation being preserved (typically by a character like a comma or a space).

Using the position of spaces as an example, we can divide the string "Python is great" into substrings to obtain a list containing only the proper nouns that had been previously separated by whitespace.

Let's take a look at an illustration to see what I mean.

String #given string1 = "Python is awesome." the string, followed by #printing the actual string is: string1; print("Actual String: "); gives us the string1 type that we asked for type(string1) = print("Type of String: ") string1 = print("String converted to list:") split()) It #displays the list passed to split().


String To List in Python A String Mapped To A Collection Of Strings

As seen in the preceding code:

  • We take into account a string, string1="Python is great," and attempt to convert the same set of component strings.
  • Using type(), we can determine that the object passed to the method is a string.
  • split() converts a string into an array using the specified delimiter. Words were separated by spaces in our code. The split() method divides the string at the spaces if no arguments are passed to it.
  • So, even though we haven't mentioned the separator parameter, the split() method still returns a list of the relevant strings.

Second, convert a string to a character list

But what if we need a catalog of every character in a string? In this case, we can use Python's list() method to directly convert strings to lists.

If the input string is "abcd," for example, we can convert it into a list by calling the list() method, which returns a list with the elements "a," "b," "c," and "d." View the sample code that we've provided down here.

To the #specified string string1="AskPython" It's time to #print the string Prints the "Real String" as "string1" Indicating the Type() and #confirming it type(string1) = print("Type of String: ") using list() to "#type-cast" the string as a list Convert a string to a list with this code: print("String converted to list:n",list(string1)).


String To List Of Characters String To Character Set Conversion

Getting a handle on the cipher:

  • This code first creates a string named string1 with the value "AskPython" and displays its type using the type() function.
  • When we typecast the string with the list() method, we get a list of the member characters, which is what we need.

3. A Sequence of Strings to a Collection of Sequences

In this article, we will examine how to combine the aforementioned techniques in order to transform a string into a collection of character enumerations.

Keep the following example in mind as you read on,

A String Value Is #Given string1 = "This is Python" The real string is: string1; print("The actual string:",string1) Putting string1 into a list of strings with the #convert command string1=string1 split() Using the #list method on each item in the list string1. list1=list(map(list,string1)) showing the resulting list of lists via #printing In other words, print("Converted to list of character list:n",list1)


String To List Of Character Lists Map Strings To Collections Of Characters

Recognize the language of the code:

  • The string string1 is initialized, and then we use the first approach to convert it into a list of strings.
  • Simply put, the current value of string1 is the list of strings defined by ['This', 'is', 'Python'].
  • When the list is complete, we run the list() method on each item.
  • string1 This yields a list of character sets, as we saw in the previous example. Please take note that the map() function was used to perform a global typecast.

Four. List to CSV

As its name implies, a CSV (Comma Separated Values) string contains values or data separated by commas.

Let's take a look at how to make a list out of such a string in Python.

The #specified string string1="abc,def,ghi" string1 = print("Real CSV String: ",string1) What is the type of this string? print("Type of string: ",type(string1)) Use ',' as the split operator for string1 to create a list. a string1 = print("CSV converted to list:") split(','))


CSV To List Extraction and Import from CSV to List


  • In a similar vein, we first imagine a string called string1 that contains several pieces of information or values separated by commas(',').
  • Once it has been printed along with its type(), we proceed to split it using the ',' parameter.
  • This results in a list whose elements are the values "abc," "def," and "ghi." By doing so, we were able to pull data from a given CSV file.

5. Convert an Integer string to an Integer List

The next step is to transform a string of only integers delimited by a space, comma, etc. add integers to a list

Take a look at the snippet of code in

Sequence of numbers delimited by spaces string1='1' > string2='2' > string3='3' > string4= The real string that contains integers is: string1.println("Real String containing integers: ",string1). type(string1) = print("Type of string: ") The string will be #converted to a list of strings. list1=list(string1 split()) the output of the command: print("String to List: ",list1) Using the map() function, we can #typecast each string in the list into an integer. list2=list(map(int,list1)) copy2 > print("List of integers: ",list2)


String With Integers To List Numbers in a String for a Checklist


  • Here, we've taken a string, string1, which was "1 2 3 4 5 6 7 8," and printed it along with its type() in order.
  • Following that, we apply the split() method and place the subset into a new list called list1. In this case, the output shows that list1 contains the values ['1', '2', '3', '4', '5', '6', '7', and '8'].
  • Now we typecast all of the list's elements as integers by applying the function int() everywhere in the list. The resulting typecast-mapped list is then saved in list2 and printed.
  • This yields an array whose elements are all integers, which can then be used in calculations.


All right, this was just a quick overview of how to use various methods to transform strings into lists. When possible, go with the solution that works best with your code, accomplishes your goal, and satisfies all of your other criteria. The comments section is open for questions.
