    A formatted string refers to a string that includes placeholders or expressions, which are dynamically replaced or evaluated to produce a final string. This allows for the creation of dynamic and readable strings by embedding variables, values, or expressions directly into the string.

    Key Concepts of Formatted Strings

    1. Placeholders: These are special markers within a string that are replaced with actual values. For example, in Python, placeholders are often denoted by {} or % symbols.

    2. Dynamic Content: Formatted strings allow you to insert variables, perform calculations, or include expressions directly within the string.

    3. Readability: They improve code readability by combining static text with dynamic content in a single, concise statement.

    Examples of Formatted Strings in Python

    Using format() Method

    The format() method replaces placeholders {} with specified values. It supports named, positional, or default placeholders.

    name = "Alice"
    age = 30
    message = "My name is {name}, and I am {age} years old.".format(name=name, age=age)
    print(message)
    # Output: My name is Alice, and I am 30 years old

    Which is better F-strings or format() in Python?
    Furthermore, using f-strings is suggested for Python 3.6 and above while .format() is best suited for Python 2.6 and above. Versions prior to Python 2.6 only provide % option for string formatting. In terms of speed, % is the fastest string formatting style.
