How to Convert a Comma-Delimited String into a List in Python?

Converting a Comma-Delimited String to a List in Python

How can I efficiently convert a string containing comma-separated values into a list? This conversion is a common task when working with data in Python.

Solution

Python's built-in str.split method provides an elegant solution for this task. It splits the string into a list of substrings based on a specified delimiter.

For a comma-delimited string, you can use the following code:

<code class="python">my_string = 'A,B,C,D,E'  # Input string
my_list = my_string.split(",")  # Split the string into a list

print(my_list)</code>

This code generates the following output:

['A', 'B', 'C', 'D', 'E']

Extension: Tuple Conversion and List Modification

If you need to convert the list to a tuple, simply use the tuple() function:

<code class="python">my_tuple = tuple(my_list)

print(my_tuple)</code>

You can also append additional elements to the list using the append() method:

<code class="python">my_list.append('F')

print(my_list)</code>

This results in an extended list:

['A', 'B', 'C', 'D', 'E', 'F']
