# 3.8:  building on the previous program, instead of printing the entire list from each line, print
# just the 1st column (the year-month-day) of each line.  (Hint:  since the string split() method
# returns a list, you can easily print just one column from that list by using a subscript (i.e.,
# index number inside square brackets after the list name).

# Expected Output:

# 19260701
