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.
