Read in the file distances.txt. It contains numbers with units meters (m), centimeters (cm) and millimeters (mm). Calculate the total distance in m and print your result to the terminal i.e. convert all numbers into the same unit, cast them to floats and calculate the sum of all numbers.
Write the result to a new file called total_distance.txt.

Content of the distances.txt

50 m
4500 cm
500 mm

## Solution 1

While we are more than willing to help those that are stuck, that doesn't mean that we are here to do it all for you! We can't do all the work, you are either getting paid for this, or it's part of your grades and it wouldn't be at all fair for us to do it all for you.

So we need you to do the work, and we will help you when you get stuck. That doesn't mean we will give you a step by step solution you can hand in!
Start by explaining where you are at the moment, and what the next step in the process is. Then tell us what you have tried to get that next step working, and what happened when you did.

If you are having problems getting started at all, then this may help: How to Write Code to Solve a Problem, A Beginner's Guide[^]

## Solution 2

See the `int` function at Built-in Functions — Python 3.10.4 documentation[^].
