I have an array:
line = ["0;\t0\n", "1;\t0\n", "2;\t0\n", "3;\t0\n", "4;\t0\n", "5;\t0\n", "6;\t0\n", "7;\t0\n", "8;\t0\n", "9;\t0\n", "10;\t0\n", "11;\t0\n", "12;\t0\n", "13;\t0\n", "14;\t0\n", "15;\t0\n", "16;\t0\n", "17;\t0\n", "18;\t0\n", "19;\t0\n", "20;\t0\n", "21;\t4,8\n", "22;\t9,5\n", "23;\t13,8\n", "24;\t18,5"]
I want to extract the values behind the semicolon. Is it possible to extract the values (0, 0, 0, ..., 4, 8, 9, 5, 13, 6 etc.)? How can I do it? I tried:
sa=line.split(";")
sa1=sa[1].delete "\n"
sa1=sa1.delete "\t"
sa1=sa1.to_i
$sa1 = sa1
When I display $sa1, I only see 18,5.
That's easy:
str = ["0;\t0\n", "1;\t0\n", "2;\t0\n", "3;\t0\n", "4;\t0\n", "5;\t0\n", "6;\t0\n", "7;\t0\n", "8;\t0\n", "9;\t0\n", "10;\t0\n", "11;\t0\n", "12;\t0\n", "13;\t0\n", "14;\t0\n", "15;\t0\n", "16;\t0\n", "17;\t0\n", "18;\t0\n", "19;\t0\n", "20;\t0\n", "21;\t4,8\n", "22;\t9,5\n", "23;\t13,8\n", "24;\t18,5"]
p str.map{|el| el.split(/;\t/)[1].chomp}
Result:
# ["0", "0", "0", "0", "0", "0", "0", "0", "0", "0", "0", "0", "0", "0", "0", "0", "0", "0", "0", "0", "0", "4,8", "9,5", "13,8", "18,5"]
