python f string with variable

In Python, F-strings (formatted string literals) provide a concise and convenient way to embed expressions inside string literals. They were introduced in Python 3.6 and have since become a popular choice for string formatting due to their readability and ease of use. In this tutorial, we'll explore the basics of F-strings and demonstrate how to use variables within them.
To use F-strings, ensure you are using Python 3.6 or a later version. You can check your Python version by running:
The basic syntax for an F-string involves prefixing the string with the letter "f" or "F" and enclosing expressions within curly braces {}. Let's look at a simple example:
In this example, the expressions {name} and {age} are replaced with the values of the corresponding variables.
F-strings support any valid Python expressions within the curly braces. This allows for more complex expressions and calculations. Here's an example:
F-strings support various formatting options to control the appearance of values within the string. For example:
In this case, :.2f specifies that the floating-point number should be formatted with two decimal places.
You can also use F-strings with dictionary values. Consider the following example:
F-strings provide a concise and expressive way to create formatted strings in Python. They are especially useful when working with variables and expressions. Remember to use Python 3.6 or later to leverage the power of F-strings in your code. Experiment with different expressions and formatting options to make your strings more dynamic and informative.
