You did well! Now let's take a look at how we can format float variables.
exact_temperature = 24.3487935543
print('The exact temperature is {:f} degrees Celsius.'.format(exact_temperature))
Result: The exact temperature is 24.348794 degrees Celsius.
The {:f} placeholder is used to print float variables. By default, it shows the float value rounded to 6 digits after the decimal point.
Exercise
Ask the user for their height and weight:
What is your height in m? What is your weight in kg?
Remember to cast the user input to a float. Then, print the following:
Your BMI is {bmi}.
Calculate the BMI as:
\text{BMI} = \frac{\text{weight\ in\ kilograms}}{(\text{height\ in\ meters})^2}
Use a float placeholder to format the result to six digits after the decimal point.
Stuck? Here's a hint!
Example inputs:
height = 1.6 weight = 50
Output:
Your BMI is 19.531250.
