Python Format String

String formatting in Python allows you to create dynamic strings by embedding variables and expressions within a string. This is useful for creating formatted output, building messages, and more.

Using f-Strings

f-Strings, introduced in Python 3.6, provide a concise and readable way to format strings. You can include variables and expressions inside curly braces {} within an f-string. For example:

const name = 'Alice';
const age = 30;

const formattedString = `My name is ${name} and I am ${age} years old.`;

The {} inside the curly braces is replaced with the value of the variable or expression. In this case, {name}is replaced with Alice and {age} is replaced with 30.

Formatting Expressions

You can also format expressions inside an f-string. For example, you can format numbers to a specific number of decimal places using {expression:.2f} to format as a float with 2 decimal places.

Conclusion

String formatting in Python using f-strings provides a powerful and flexible way to create dynamic strings. By embedding variables and expressions within a string, you can easily create formatted output tailored to your needs.
