Split a string into a list of whitespace-separated tokens.

Express the operation of tokenizing a string by whitespace.

When you need to parse a string into words or tokens separated by spaces, tabs, or newlines.

Text processing, parsing user input, preparing data for iteration or analysis.

s.split()

object.method() where object is a string

s: any string expression

• strip
• splitlines
• partition

• s.split(sep) for custom separator
• re.split(pattern
• s) for regex

Assuming split() returns empty strings for leading/trailing whitespace; it does not.

s.split(sep) vs s.split(); s.partition(sep) vs s.split(sep); s.strip() vs s.split()

In languages with immutable strings, split returns a new list; be aware of immutability vs mutability assumptions.

• s.strip()
• s.splitlines()
• s.partition(sep)
• s.split(sep)

split() treats any consecutive whitespace as a single delimiter and does not produce empty strings for leading/trailing whitespace.

Produces a list of tokens ready for iteration or further processing.

Think of splitting a sentence into words.

Equivalent to str.split() in Python; similar to String.split() in Java.
