Answer:
def sublist(aList):
 new_list = []
 for s in aList:
 if len(s) < 4:
 new_list.append(s)
 
 return new_list
Step-by-step explanation:
Create a function called sublist that takes one parameter, aList
Inside the function, create a new_list that will hold the strings which are less than 4 characters. Create a for loop that iterates through the aList. If a string in aList is less than 4 characters, add it to the new_list. When the loop is done, return the new_list
