{price:f}

Definition

{price:f} is a format specifier used in Python's f-strings (formatted strings) to display a floating-point number. It allows for the precise formatting of decimal values, making it useful for displaying prices, measurements, and other numerical data with a specific number of decimal places.

5 Must Know Facts For Your Next Test

1. {price:f} is used to format a floating-point number with a specific number of decimal places, typically for displaying prices or other numerical data.
2. The 'f' in {price:f} stands for 'fixed-point', which means the number of decimal places is fixed and will not change based on the value.
3. You can specify the number of decimal places to display by adding a number after the 'f', such as {price:2f} for two decimal places.
4. Using {price:f} ensures that the decimal places are consistently displayed, which is important for maintaining a clean and professional appearance in your output.
5. {price:f} is commonly used in financial applications, e-commerce platforms, and any other scenarios where precise numerical formatting is required.
