Help! How do you do this challenge?

My loopy function needs to skip an item this time, though. Loop through each item in items again. If the character at index 0 of the current item is the letter "a", continue to the next one. Otherwise, print out the current member. Example: ["abc", "xyz"] will just print "xyz".

breaks.py 
def loopy(items):
    # Code goes here
    for things in items:
        if things.index("a") = 0:
            continue
        else:
            print(things)

Here are the steps:

  • Iterate over each item in items using for loop
  • check if first character of each item is an "a"
  • if not, print item

Post back if you need more help. Good luck!

How do you check if first character of each item is an "a"?

In a loop of item in items, the test would be:

item[0] == "a"

This code:

def loopy(items):
    # Code goes here
    for item in items:
        if item[0] = "a":
            continue
        else:
            print(item)

is still not working.

Be sure to use a comparison ==, and not an assignment = operator
