The str.split() Function Syntax

The str.split() function splits a string into a list of substrings based on a specified delimiter. It does not modify the original string but returns a list of substrings.

Here's the basic syntax:

Python
string.split(sep)

Example:

Python
text = "Hello, World!"
split_text = text.split(", ")
print(split_text)  # Output: ["Hello", "World!"]

In this example, the str.split() function splits the text into a list of substrings based on the delimiter ", ".

Practical Use Cases

The str.split() function is often used in scenarios where text data needs to be parsed or processed.

Example:

Python
csv_data = "name,age,city"
fields = csv_data.split(",")
print(fields)  # Output: ["name", "age", "city"]

In this example, the str.split() function splits a CSV string into a list of fields.
