Python string methods
In Python, a string is a sequence of characters enclosed in quotes (either single quotes ' ' or double quotes " "). Strings can contain letters, numbers, symbols, and whitespace. They are immutable, meaning they cannot be changed after creation.
Here are some key characteristics of Python strings:
1. *Immutable*: Strings cannot be modified after creation.
2. *Sequence*: Strings are a sequence of characters, allowing indexing and slicing.
3. *Unicode*: Python strings support Unicode characters, allowing for internationalization.
4. *Quoted*: Strings are enclosed in quotes (single ' ' or double " ").
5. *Case-sensitive*: String comparisons are case-sensitive.
Examples of Python strings:
'Hello, World!'
"Python is fun!"
'123' (a string containing digits)
' ' (a string containing only whitespace)
String literals can also use various prefixes to specify the type of string:
`r` prefix: Raw string (ignores escape sequences)
`b` prefix: Byte string (contains bytes instead of Unicode characters)
`f` prefix: F-string (allows embedded expressions and formatting)
For example:
`r'C:\Windows'` (raw string)
`b'Hello'` (byte string)
`f'My name is {name}'` (f-string)
