> [!note] String Concatenation  
> The `+` operator, when used with two strings, combines them into a single new string — this is called **string concatenation**.  
> 
> > [!example] Examples  
> > ```python
> > 'Alice' + 'Bob'           # AliceBob
> > 'Alice' + 42              # TypeError: can only concatenate str (not 'int') to str
> > 'Alice' + str(42)         # Alice42
> > 'Alice' * 5               # AliceAliceAliceAliceAlice
> > 
> > name = "Al"
> > print("It is good to meet you, " + name)  # It is good to meet you, Al
> > ```
> 
> > [!important] Best Practices  
> > - Ensure both operands are strings before using `+`  
> > - Prefer `f-strings` or `format()` for cleaner code when mixing types  
> > ```python
> > f"Alice{42}" # Alice42
