Formatting Fixed Digits after Decimal with f-Strings

f-strings provide a convenient way to format strings in Python. However, achieving fixed digits after the decimal point may require additional consideration. This article addresses this issue and explains how to use type specifiers to control the number of decimal digits displayed in f-strings.

To format a float value with a fixed number of digits after the decimal, include the type specifier .nf in the format expression. Here, n represents the desired number of digits. For example, .2f specifies two decimal digits.

<code class="python">a = 10.1234
fixed_digits = f'{a:.2f}'  # Display with 2 decimal digits</code>

In this example, the value of fixed_digits will be '10.12', truncating the additional digits after the second decimal place. This technique can be applied to any float value, providing precise control over the decimal formatting.
