Certainly! Let's examine the Python code and its application in a real-world scenario:
Python Code Explanation:
# Assigning an integer to variable 'age'
age = 36
# Creating a formatted string with an f-string that includes the 'age' variable
txt = f"My name is John, I am {age}"
# Printing the formatted string
print(txt) # Output: My name is John, I am 36
In this code, an f-string is used, which is a string literal prefixed with 'f' that allows expressions to be embedded directly within the string. The {age} within the f-string txt is replaced by the value of the age variable when the string is printed.
Real-World Example:
F-strings are incredibly useful for dynamic text generation where the content changes based on variables. For instance, in a web application, you might use f-strings to generate personalized welcome messages for users based on their profile information.
Here's how it might look in a web app:
# User profile information
user_name = "Jane"
user_age = 28
# Generating a personalized welcome message using an f-string
welcome_message = f"Welcome back, {user_name}! You are {user_age} years old."
# Displaying the welcome message on the website
print(welcome_message) # Output: Welcome back, Jane! You are 28 years old.
In this example, the f-string is used to create a custom message that includes the user's name and age. This method is widely used in software development for creating dynamic strings that need to incorporate variable data, such as user information, dates, or any other type of data that might change¹². It's a powerful feature that makes string formatting more intuitive and readable.

Certainly! The Python code you've provided is an example of string formatting using f-strings, which is a feature introduced in Python 3.6. Here's a breakdown of the code and a real-world example:
txt is a formatted string (denoted by the f before the quotation marks) that includes the price variable.
{price:.2f} within the string is a placeholder for the price variable. The :.2f part is a format specifier, meaning that the number should be formatted with 2 decimal places.
Finally, print(txt) outputs the string to the console.
Real-world example:
Imagine you're writing a program for a coffee shop. They sell lattes for $3.50, and you want to print out the price with tax. Here's how you could use the code:
# Price of a latte
latte_price = 3.50
# Tax rate
tax_rate = 0.07
# Total price calculation
total_price = latte_price + (latte_price * tax_rate)
# Formatted output
txt = f"The total price with tax is {total_price:.2f} dollars"
print(txt)
When you run this code, it will calculate the total price including tax and print:
The total price with tax is 3.75 dollars
This demonstrates how you can use f-strings to dynamically insert variables into strings and format them nicely for user-friendly output, which is very useful in applications that involve financial transactions, such as point-of-sale systems or online shopping platforms.
