String Types in Python with Examples

In Python, a string is a sequence of characters enclosed in quotes. Python supports various ways to define and manipulate strings. Strings are one of the most commonly used data types.

1. Single-line Strings

You can define strings using single (' '), double (" "), or **triple (''' ''' or """ """) quotes.

Examples:

s1 = 'Hello'
s2 = "World"
print(s1, s2)  # Output: Hello World

Both s1 and s2 are simple single-line strings.

2. Multi-line Strings

Use triple quotes to define multi-line strings.

Example:

paragraph = """This is a
multi-line string
in Python."""
print(paragraph)

3. Raw Strings

Raw strings treat backslashes (\) as literal characters. Prefix the string with r or R.

Example:

path = r"C:\Users\Name\Documents"
print(path)  # Output: C:\Users\Name\Documents

Without r, Python might interpret \n as a newline.

4. Unicode Strings

In Python 3, all strings are Unicode by default, so you can include non-ASCII characters.

Example:

greeting = "नमस्ते"
emoji = "🙂"
print(greeting, emoji)  # Output: नमस्ते 🙂

5. Formatted Strings (f-strings)

Introduced in Python 3.6, f-strings allow embedded expressions inside string literals, using {}.

Example:

name = "Alice"
age = 25
print(f"My name is {name} and I am {age} years old.")

6. Byte Strings

Byte strings are sequences of bytes rather than characters. Prefix the string with b.

Example:

byte_str = b"Hello"
print(byte_str)         # Output: b'Hello'
print(type(byte_str))   # <class 'bytes'>

Useful when working with binary data or network programming.
