Not sure why I'm getting an Assertion Error

My output is correct or at least it looks correct to me, but after the second time it was run, I'm getting a 'Assertion Error.'

continents.py 
continents = [
    'Asia',
    'South America',
    'North America',
    'Africa',
    'Europe',
    'Antarctica',
    'Australia',
]
# Your code here
for continent in [0, 1, 2, 3, 4, 5, 6]:
    print("* ", continents[continent])

It's not obvious from the output, but comma-separated arguments to print() are output with a space between then. Since the first item includes a space in "* ", then effectively there are two spaces.

So I assume you just delete the white space and all is good?

Correct. You can:

  • remove the white space
  • add the sep='', argument to print()
  • use a formatted string such as:
    • f"* {continent}"
    • "* {}.format(continent)"`
    • "* %s" % continent

My apologies, Chris! I must have clicked it by accident.

Treehouse allows markup for "thumbs up". Using ":thumbsup:" or ":+1:" ==> :thumbsup:

I am really lost, this is the way I did it, however, I have not found any instructions on the "f" function uses.

continents = [
    'Asia',
    'South America',
    'North America',
    'Africa',
    'Europe',
    'Antarctica',
    'Australia',
]
# Your code here

for continent in continents:
    if  continent(0) == 'A':
    print("* "+ continent)

Very close. continent isn’t a function which is what the parens imply. Use continent[0] instead.
