Hey Tanzila Rafeeq, parsing items in lists is a common Python task.

A useful way to check each item in a list is using the for loop, of the form:

for item in my_list:
    # do something with item

In this challenge, it would be to print the item.

If you need to filter the items, that is, only do something with certain items, an if statement can be used to see if the item meets the criteria:

if <conditional_statement>:
    # proceed to do something

Examples of conditional statements:

  • item[0] == "A"
  • item.startswith("A")

Post back if you need more help. Good luck!!
