Printing labels with certain letters

I'm drawing a huge blank on how to print certain labels that have a specific letter in the start. I've looked at my notes and can't figure it out.

continents.py 
continents = [
    'Asia',
    'South America',
    'North America',
    'Africa',
    'Europe',
    'Antarctica',
    'Australia',
]
print(continents)
for continent in continents:
    print("* " + continent)

Exactly what Megan said! This would be a great time to use an 'if' statement so let's say you have a list that you only want to display the names starting with M:

names = [
    'Mel',
    'Carlos',
    'Megan',
    'Mary',
    'Joe',
    'Alex'
]

for name in names:
    if name[0] == "M":
        print(f"* {name}")

This would output

  • Mel
  • Megan
  • Mary

You can access specific characters in a string just like you access items in a list with indexing. For example, if I wanted to access the second character in animal = 'cat', I would print(animal[1]).

Thank you both so much I wrote down the correct code I just didn't understand it until now.
