bookAdvanced Formatting: Float, Round, and Percent

Within a simple {} block, we can round a float number with the necessary precision, or represent a number as a percent.

Let's consider the pattern we will use in this chapter:

{:[thousands separator].[number][type]}

Please note, that like in the previous chapters, we don't need to place square brackets (I placed it for convenience).

  • [thousands separator] - the symbol used to separate every thousand (possible values are , and _).
  • [number] - is the precision, number of decimal places (used for rounding number).
  • [type] - type of number representing (e - scientific notation, % - percentage (will multiply number by 100), g - general format, f - fixed-point notation). You can dive deeper into possible options in Python documentation.

print("Original number: {0}, formatted number: {0:.2f}".format(255/8))
print("Original number: {0}, formatted number: {0:.2%}".format(15/48))
print("Original number: {0}, formatted number: {0:,.2f}".format(35*6327))

As of 2020, the population of the USA was 331002651. The total land area is 9147420 sq.km. Population density is the population-to-area ratio. Your tasks are:

  1. Format the first string so the population and area will be printed in format: 9,147,420, and insert variables in the correct order.
  2. Within the second .format function calculate the population density and format the number in format 28.45.
