PYTHON — Round Numbers Exercise in Python

Any fool can write code that a computer can understand. Good programmers write code that humans can understand. — Martin Fowler

In this exercise, you will learn how to round a number to two decimal places in Python. The goal is to get a number from the user and display it rounded to two decimal places without relying on the format specification mini-language.

# Get a number from the user
number = float(input("Enter a number: "))

# Round the number to two decimal places
rounded_number = round(number, 2)

# Display the rounded number
print(f"The rounded number is: {rounded_number}")

In the code snippet above, the input function is used to get a number from the user as a string, which is then converted to a floating-point number using the float function. The round function is then used to round the number to two decimal places, and the result is displayed using the print function.

By running the code and entering a number when prompted, you can see the rounded number displayed to two decimal places. This exercise demonstrates how to achieve this without relying on the format specification mini-language.
