The list ["4", "x", "7", "3"] holds texts. Convert each one to a whole number, skip the ones that fail, and add up the good ones.
Need a reminder? The key ideaShow
try inside a loop lets the loop go on after a bad value.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, compare your working with the solution.
Plan. A loop over the texts. In each round, try to convert and append to a new list. If a ValueError happens, show skipping and the text.
The good values are , and . The text x is skipped. The sum is .
