Problem 1 (to get the idea)

• Given a list of lines L, shown below, write a program that generate the list of the line numbers for lines containing words starting with 'a' and ending with 'z'.

L = [ "------- --------- -------- --- - --------- ---------",           # line 0
       "------- ---------- a----z -------- -- --------- --------",      # line 1
       "------- ---------- ------ -------- -- --------- --------",      # line 2
       "------- ---------- ------ -------- -- --------- --------",      # line 3
       "------- ---------- ------ -------- az --------- --------",      # line 4
       "------- ---------- ------ -------- -- --------- --------" ]     # line 5

• For the example above, the result would be a list newL = [ 1, 4 ].

Problem 2 (the real problem)

• Same idea, but we want to get the first line that contains such a word.
