Advanced Formatting Options
When you need to control exactly how numbers and text appear in your output, advanced formatting options in Python's f-strings give you powerful tools. You can specify decimal precision for floating-point numbers, control the width of fields, and align text for clear, readable tables. These features are especially useful when you want your data to look professional and well-organized, such as when displaying financial figures or tabular data.
12345678910111213141516# Formatting floating-point numbers to two decimal places price = 12.3456 formatted_price = f"{price:.2f}" print(f"Price: {formatted_price}") # Aligning text in columns using width specifiers and alignment header1 = "Product" header2 = "Price" row1 = "Apple" row2 = "Banana" price1 = 1.25 price2 = 0.75 print(f"{header1:<10} | {header2:>7}") print(f"{row1:<10} | {price1:>7.2f}") print(f"{row2:<10} | {price2:>7.2f}")
You can also format integers with leading zeros by using the 0 character in your width specifier. This is helpful for things like invoice numbers, timestamps, or any case where you want a number to always appear with a fixed number of digits. The width specifier controls the minimum number of characters for the field, padding with spaces or zeros as needed. For example, f"{5:03}" will display 005. Alignment specifiers like <, >, and ^ can be used to left-align, right-align, or center text within a given width, making your output easy to read.
1. How do you format a float to display two decimal places using an f-string?
2. Which format specifiers can be used for text alignment in f-strings?
