A string in Python is a sequence of characters used to represent text. It can include letters, numbers, symbols, and whitespace. Strings are created by enclosing characters in either single quotes (' '), double quotes (" "), or triple quotes (''' ''' or """ """) for multi-line strings
. Python strings are immutable, meaning once a string is created, its content cannot be changed. Any modification creates a new string rather than altering the original
. Strings in Python are indexed starting at zero, allowing access to
individual characters using square brackets, e.g., string for the first
character. Python also supports slicing to extract substrings using the syntax
string[start:end]
. Python provides a built-in string class called str with many useful
methods for string manipulation, including concatenation with the +
operator, formatting, and more advanced operations
. In summary:
- A string is a sequence of characters.
- Strings are enclosed in quotes.
- Strings are immutable.
- Characters can be accessed by indexing and slicing.
- Python’s
strclass offers many built-in methods for working with strings.
This makes strings a fundamental data type for handling textual data in Python programming
