829 PointsHow can I just print the elements begin with an "A"?
I know that I need to use indexing, but I still don't know how to do it.
continents = [
'Asia',
'South America',
'North America',
'Africa',
'Europe',
'Antarctica',
'Australia',
]
As = continents
del As[1]
del As[1]
del As[2]
for A in As:
print("*", A)

continents = [
"Asia",
"South America",
"North America",
"Africa",
"Europe",
"Antarctica",
"Australia",
]
for obj in continents:
if obj[0] == "A":
print(obj)
When you are looping through the list of continents, obj[0]
is the first letter (index) of each continent.

In the conditional expression you can compare the first letter of the name (using indexing) to see if it is equal to "A".
