Review Questions

• Explain how the {percentage:%} specifier is used within a formatted string in Python.
  • The {percentage:%} specifier is used within a Python formatted string (f-string) to display a numeric value as a percentage. For example, if you have a variable 'value' with a decimal value of 0.75, you can use the f-string 'f'{value:{percentage:%}}'' to display it as 75%. The {percentage:%} specifier automatically formats the value as a percentage, including the % symbol. You can also control the number of decimal places displayed by using the format {percentage:.2f}%, which would show the value as 75.00%.
