Transforming Comma-Delimited Strings to Python Lists

Given a string containing a series of comma-separated values, it is desirable to convert it into a Python list. This transformation aids in further data analysis and manipulation.

To achieve this, leverage the str.split method:

my_string = 'A,B,C,D,E'
my_list = my_string.split(",")
print(my_list)

This yields a list of strings: ['A', 'B', 'C', 'D', 'E']. If a tuple is preferred, simply enclose the list in parentheses:

print(tuple(my_list))

For appending to an existing list, utilize the .append method:

my_list.append('F')
print(my_list)

This appends 'F' to the list, resulting in ['A', 'B', 'C', 'D', 'E', 'F'].
