How To Convert Comma-Delimited String to a List In Python?

In Python, converting a comma-separated string to a list can be done by using various methods. In this article, we will check various methods to convert a comma-delimited string to a list in Python.

Using str.split()

The most straightforward and efficient way to convert a comma-delimited string to a list is by using Python’s built-in split() method. This method works by splitting the string based on a given delimiter.

s = "geeks,for,geeks"

p = s.split(',')
print(p)

['geeks', 'for', 'geeks']

Explanation:

• In this example, split(',') divides the string s at each comma and puts each part (like 'geeks', 'for') into a list p.

Using map() with split()

map() function applies the split() method to each element of the string, which can be useful in more complex scenarios, such as if we need to apply additional transformations after splitting.

s = "geeks,  for,geeks"

r= list(map(str, s.split(',')))
print(r)

['geeks', '  for', 'geeks']

Using List Comprehension

We can use list comprehension for splitting and further processing, such as removing whitespace or converting elements.

s = "Geeks,for,geeks"

r = [item.strip() for item in s.split(',')]
print(r)

['Geeks', 'for', 'geeks']
