Python – Split String by Comma

In this tutorial, we will look at how to split a string into a list of strings on the occurrences of a comma in Python with the help of examples.

How to split a string in Python?

Split a string in python by comma

You can use the Python string split() function to split a string (by a delimiter) into a list of strings. To split a string by comma in Python, pass the comma character "," as a delimiter to the split() function.

The following is the syntax –

# split string s by comma
s.split(",")

It returns a list of strings resulting from splitting the original string on the occurrences of ",".

Let’s look at some examples.

Split string by comma

Here, we pass comma "," as the delimiter to the string split() function.

# string with commas
s = "Yes, they backed Steve, Emma, and Rohan in the meeting."
# split string by comma
ls = s.split(",")
print(ls)

Output:

['Yes', ' they backed Steve', ' Emma', ' and Rohan in the meeting.']

The resulting list contains words resulting from the split of the original string on occurrences of a comma.

Fix the number of splits

You can also specify the maximum number of splits to be made using the maxsplit parameter. By default, the string split() function makes all the possible splits.

Let’s only split the above string into two parts at the occurrence of a comma, ","starting from the left. To split the string into two parts, the maxsplit should be 1, because we’re making only one split resulting in two strings.

# string with commas
s = "Yes, they backed Steve, Emma, and Rohan in the meeting."
# split string by comma
ls = s.split(",", maxsplit=1)
print(ls)

Output:

['Yes', ' they backed Steve, Emma, and Rohan in the meeting.']

You can see that the resulting list has only two strings.

Let’s look at another example.

Let’s split the original string into three parts, here we pass maxsplit=2.

# string with commas
s = "Yes, they backed Steve, Emma, and Rohan in the meeting."
# split string by comma
ls = s.split(",", maxsplit=2)
print(ls)

Output:

['Yes', ' they backed Steve', ' Emma, and Rohan in the meeting.']

The resulting list has only three strings.
