PYTHON — Limit Decimal Places Exercise in Python

Talk is cheap. Show me the code. — Linus Torvalds

In this tutorial, we’ll practice formatting numeric values as Python strings. You’ll be given an arithmetic expression and be tasked with printing its result using only three decimal places.

Let’s start with an example of an arithmetic expression. Suppose we have the following expression:

result = 10 / 3

We want to display the result with only three decimal places. Here’s how we can do that in Python:

result = 10 / 3
formatted_result = "{:.3f}".format(result)
print(formatted_result)

In this example, we use the format method with the "{:.3f}" format specifier to round the result to three decimal places.

Let’s move on to another example. Consider the expression:

result = 7 / 2

Again, we want to print the result with only three decimal places.

result = 7 / 2
formatted_result = "{:.3f}".format(result)
print(formatted_result)

By using the format method with the "{:.3f}" format specifier, we can limit the result to three decimal places.

You can use the same approach to format other numeric values in Python. Remember to use "{:.3f}" to limit the decimal places to three.

That concludes our exercise on limiting decimal places in Python. With these examples, you should now be comfortable formatting numeric values as Python strings with a specific number of decimal places.
