I can't fix this... [Python]

Hey, I got a problem. I realy don't know how to do this. Can some one explain it to me? The question is: Print a bulleted list of each continent from the continents list. Output should look similar to:

continents.py
continents = [
    'Asia',
    'South America',
    'North America',
    'Africa',
    'Europe',
    'Antarctica',
    'Australia',
]
# Your code here
count = 0
for 'Asia' in continents:
    count += 1
    for 'South America' in continents:
        print('')
else:
    del continents[count]
    count += 1

You've got the right idea, but there's a few issues, Here's a few hints:

  • you don't need a "count" for this challenge
  • you only need one loop
  • you don't need an "else" or anything after it (particularly no "del"!)
  • a loop argument must be a variable name instead a constant (like "for item in continents:")
  • the "print" statement must contain what you want to print
  • you can use concatenation (+) to combine a constant string (like "* ") with a variable

It looks like your part 2 solution has an extra loop that is checking every letter of the continent. But the challenge instructions only ask you to check the first letter of the continent.

Also, to make your code readable it needs to be formatted with "Markdown". Use the instructions for code formatting in the Markdown Cheatsheet pop-up below the "Add an Answer" area. :arrow_heading_down:   Or watch this video on code formatting.

continents = [ 'Asia', 'South America', 'North America', 'Africa', 'Europe', 'Antarctica', 'Australia', ]

Your code here

for continent in continents: for letter in continent: if letter[0] == "A": print("* " + continent) Hey, I did the first question.. But there is a second question... The problem is that North America and South America are printed... I need to print every continent that's starts with the letter 'A'.
