    The str.format() method in Python allows you to insert variables or values into a string using placeholders {}, making it a powerful tool for creating dynamic and well-formatted output.

    Example:

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

    1. Positional and Keyword Arguments You can reference placeholders by position or by name.

    print("{1} loves {0}!".format("Python", "Alice"))
    # Output: Alice loves Python!

    print("{lang} is fun!".format(lang="Python"))
    # Output: Python is fun!
    Copied!

    This improves readability and flexibility when formatting strings.

    2. Number Formatting & Alignment The : inside {} lets you control alignment, width, precision, and type.

    num = 1234.56789
    print("{:<15}".format("left")) # Left align
    print("{:>15}".format("right")) # Right align
    print("{:^15}".format("center")) # Center align
    print("{:.2f}".format(num)) # 2 decimal places
    print("{:,}".format(1000000)) # Thousand separator
    Copied!

    Output:

    left
    right
    center
    1234.57
    1,000,000
    Copied!
    What is format method in Python?
    format () method in Python is a tool used to create formatted strings. By embedding variables or values into placeholders within a template string, we can construct dynamic, well-organized output. It replaces the outdated % formatting method, making string interpolation more readable and efficient. Example: My name is shakshi and I am 22 years old.
