How can I format a number to display two decimal places using Python\'s f-strings?

Fixed Digits After Decimal with f-Strings

Many programming languages offer a way to format numbers as strings with a specific number of decimal places. How can we achieve this with Python's f-strings?

Problem:

Assume we have a value a that needs to be displayed with two digits after the decimal point. How can we use f-strings to accomplish this?

Answer:

By including the type specifier .2f in the format expression, we can specify that we want two fixed digits after the decimal point. For example:

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

This will print '10.12', where the decimal value has been truncated to two digits.
