How can I display a fixed number of digits beyond the decimal point in Python using f-strings?

Displaying Fixed Digits Beyond Decimal Using f-Strings

f-strings offer a convenient method for formatting and displaying Python variables. If you need to specify a fixed number of digits after the decimal point, the solution lies in utilizing type specifiers within the format expression.

Type Specifiers for Digits

To specify the number of decimal places, include a type specifier in the format expression following the placeholder. The type specifier begins with a period (.) and is followed by the number of digits you want to display.

For example, to display 2 digits after the decimal point, use the format string ".2f".

Example

Let's say we have a float variable a with a value of 10.1234. To display it with 2 decimal places, we can use the following f-string:

<code class="python">>>> a = 10.1234
>>> f'{a:.2f}'</code>

This will output the string '10.12', showing only the first 2 digits after the decimal point.
