I got a list from a datafile:
ctxt = Flatten[ StringSplit[Import["d.txt", "Data"], ","]];
Then I got every third number:
lst3 = ctxt[[3 ;; ;; 3]];
When "looked" at lst3 in an outcell it looked like a list of numbers {79, 2, 8, 54 ...}
But it is actually a list of strings: {"79", "2", "8", "54" ...}
It took me a long time to make this realization and to fix my code:
lst3 = ToExpression /@ ctxt[[3 ;; ;; 3]];
What is going on? Why does the outcell "look" incorrect?
Thanks in advance
