When you use the list as the loop variable ("for continents in continents:"), the loop will alter the list as it runs.

To prevent this, give the loop variable a different name.

Instead of "for continents in continents:" you might write "for item in continents:".

When the list name is a plural word, it's also popular to use the singular version (without the "s") as the loop variable:

for continent in continents:

Maybe you forgot to change the "print" statement to use the new variable name?
