Python Basics Challenge - Continue

I'm having a lot of trouble trying to figure this exercise out - I would appreciate some assistance - Here is my code thus far: 

def loopy(items):
    # Code goes here
    for i in items:
        if i(0) == 'a':
        continue
    print(i)

AND

Here is the exercise I'm working on:

Same idea as the last one. 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".

I tried indenting continue, and I keep getting this message: "Str object is not callable" - So, I erase the indent, and that still doesn't work - I've also tried several other approaches, but I just don't know what I'm missing...

You're close, but I see a few issues:

  • indexing is done with brackets :point_right:[]:point_left:, not parentheses :point_right:():point_left:
  • anything inside a loop must be indented further than the for statement itself
  • any conditionally-executed statements must be indented further than the if statement itself

Your for loop has to be for item in items, not i in items.

Actually, the name of the "temporary" variable used in a loop doesn't matter.

It can be whatever your heart desires, as long as it is a Valid Python name.

Just to recap:

  • Variables must have only letters, numbers, and underscores _
  • Variable names can't start with a number (or Python will think it is a number)
  • No special characters other than underscores! (for example, #%^$(*& are all not allowed. Keep in mind this includes spaces!)
  • No dashes (- represent a dash)! Python will think you are trying to do subtraction!
